Case-insensitive matching helpers

EqualFold, IndexFold, ContainsFold, HasPrefixFold, and HasSuffixFold compare ASCII case-insensitively using the SWAR word loops: only A..Z/a..z fold, every other byte (including bytes

= 0x80) must match exactly. HasPrefixFold and HasSuffixFold cover the header checks Fiber otherwise spells as an allocation-prone ToLower + HasPrefix/HasSuffix pair (authorization schemes such as Bearer, content-type prefixes such as multipart/form-data, suffixes such as +json), and like the other Fold helpers they take the needle as a plain string because call sites pass constant tokens. Their Benchmark_HasPrefixFold/Benchmark_HasSuffixFold numbers are tracked on the benchmark charts and join the catalog above on its next regeneration.

SWAR primitives

The swar package exports the SWAR (SIMD within a register) building blocks the helpers above are composed from: Load8/Store8, Broadcast, ZeroLanes, MatchByteMask/MatchRangeMask, ToLowerWord/ToUpperWord, FirstLane/LastLane, and the WordLen, Ones, HighBits, and LowSeven constants. They are exported so downstream packages (Fiber itself, middleware) can fuse their own byte scans — for example, finding a delimiter while classifying the bytes before it — without re-deriving the bit tricks. The contracts (unchecked bounds preconditions, ZeroLanes' approximate mask, the little-endian lane order) and runnable examples live in the package documentation.

The package benchmarks its primitives against their stdlib counterparts the same way the helpers above do, measuring the canonical loops composed from them: Load8/Store8 vs encoding/binary's little-endian Uint64/PutUint64, a ZeroLanes first-match scan vs strings.IndexByte, a MatchByteMask+LastLane reverse scan vs bytes.LastIndexByte, a MatchRangeMask digit scan vs strings.IndexAny, and an in-place ToLowerWord loop vs bytes.ToLower. The composed loops are pinned to the stdlib results by a dedicated test, and the numbers are tracked per commit on the benchmark charts. Note that strings.IndexByte is hand-written SIMD assembly and overtakes the portable SWAR scan on large inputs; the SWAR primitives earn their keep on short HTTP-sized inputs and on fused scans the stdlib has no single function for. The package's remaining benchmark, Benchmark_Load8_Fusion, is an advisory codegen guard rather than an API performance promise, so it is deliberately not part of the catalog above.

SIMD-accelerated search (package simd)

The simd package is the vector-width counterpart to swar: byte searching and validation whose scan kernels dispatch to AVX2 assembly (32 bytes per iteration) on amd64 CPUs for inputs of simd.MinLen (32) bytes or more, and fall back to portable loops built on the swar primitives everywhere else, so it builds and behaves identically on every platform. simd.Accelerated() reports which mode is active. CPU capability detection uses golang.org/x/sys/cpu, which also verifies OS support for saving the vector register state.

The AVX2-backed kernels are the multi-needle scans (Memchr2, Memchr3), the paired-byte scan (MemchrPair), the class scans (MemchrDigit/MemchrDigitAt, MemchrWord/MemchrNotWord), ASCII validation (IsASCII), and the substring search (Memmem), which prefilters on the needle's rarest bytes (SelectRareBytes, ByteRank) before verifying candidates — 2-6 byte needles containing two distinct values are scanned for their two rarest bytes at the exact relative distance, longer or single-valued needles for the single rarest byte. Two smaller tiers are documented explicitly: FirstNonASCII and CountNonASCII are SWAR-only (8 bytes per iteration, no assembly kernel), and MemchrInTable/MemchrNotInTable are plain scalar loops, since an arbitrary 256-entry membership test has no cheap vector form. There is deliberately no single-needle Memchr: bytes.IndexByte is already vector-accelerated by the Go runtime. Memmem delegates to bytes.Index below 128 bytes — a conservative routing point above the paired scan's measured break-even (Benchmark_Memmem_Prefilter forces the prefilter helpers at every size to keep it measurable) — and bails to bytes.Index after a bounded number of failed candidate verifications, so even adversarial inputs — a rare byte everywhere plus a long almost-matching needle — stay within a constant of the stdlib's O(n+m) (see Benchmark_Memmem_Adversarial). The package operates on []byte only; the generic top-level helpers IsASCII, IndexAny2, and IndexAny3 dispatch into it automatically for inputs of simd.MinLen+ bytes on amd64, which is where the AVX2 kernels overtake the SWAR word loops (-35% to -88% ns/op at 32-512B in benchstat -count=10 runs; shorter inputs keep the existing SWAR paths).

The kernels are adapted from the coregex project's simd package (MIT License, Copyright (c) 2025 Andrey Kolkov and contributors; see simd/LICENSE), with the legacy-SSE register moves in the kernels replaced by VEX-encoded ones to avoid AVX-SSE transition stalls, the scalar tail loops replaced by overlapping vector rescans at the buffer end (a 63-byte scan previously cost ~3.7x a 64-byte one), and the fallbacks reworked around the stdlib and the swar package as described above.

Because the AVX2 kernels only engage on amd64, their benchmark numbers are recorded separately from the arm64 catalog above:

Functions

func AddTrailingSlashBytes 

func AddTrailingSlashBytes(b []byte) []byte

AddTrailingSlashBytes appends a trailing '/' to b if it does not already end with one. If the input already ends with '/', the original slice is returned. A new slice is returned when a '/' is appended. The original slice is never modified.

func AddTrailingSlashString 

func AddTrailingSlashString(s string) string

AddTrailingSlashString appends a trailing '/' to s if it does not already end with one. If the input already ends with '/', the original string is returned. A new string is returned only when a '/' needs to be appended.

func AppendInt 

func AppendInt(dst []byte, n int64) []byte

AppendInt appends the decimal string representation of n to dst.

func AppendUint 

func AppendUint(dst []byte, n uint64) []byte

AppendUint appends the decimal string representation of n to dst.

func ByteSize 

func ByteSize(bytes uint64) string

ByteSize returns a human-readable byte string of the form 10M, 12.5K, and so forth. The unit that results in the smallest number greater than or equal to 1 is always chosen. Maximum supported input is math.MaxUint64 / 10 (≈ 1844674407370955161).

func ContainsFold added in v2.1.2 

func ContainsFold[S byteSeq](s S, needle string) bool

ContainsFold reports whether s contains needle, ASCII case-insensitively.

func ConvertToBytes 

func ConvertToBytes(humanReadableString string) int

ConvertToBytes returns integer size of bytes from human-readable string, ex. 42kb, 42M Decimal units are powers of 1000 (42k = 42000); binary units with an 'i' infix are powers of 1024 (42Ki = 43008). Note that ByteSize formats with powers of 1024, so use binary suffixes for a lossless round-trip. Returns 0 if the string is unrecognized or negative.

func CopyBytes 

func CopyBytes(b []byte) []byte

#nosec G103 CopyBytes copies a slice to make it immutable

func CopyString 

func CopyString(s string) string

CopyString copies a string to make it immutable

func FunctionName 

func FunctionName(fn any) string

FunctionName returns function name

func GenerateSecureToken 

func GenerateSecureToken(length int) string

GenerateSecureToken generates a cryptographically secure random token encoded in base64. It uses crypto/rand for randomness and base64.RawURLEncoding for URL-safe output. If length is less than or equal to 0, it defaults to 32 bytes (256 bits of entropy). Panics if the random source fails.

func GetArgument 

func GetArgument(arg string) bool

GetArgument check if key is in arguments

func GetMIME 

func GetMIME(extension string) string

GetMIME returns the content-type of a file extension

func HasPrefixFold added in v2.2.0 

func HasPrefixFold[S byteSeq](s S, prefix string) bool

HasPrefixFold reports whether s begins with prefix, ASCII case-insensitively: only 'A'..'Z'/'a'..'z' fold, every other byte (including >= 0x80) must match exactly, mirroring IndexFold. An empty prefix matches any s. Like the other Fold helpers the needle is a plain string, since call sites pass constant tokens.

func HasSuffixFold added in v2.2.0 

func HasSuffixFold[S byteSeq](s S, suffix string) bool

HasSuffixFold reports whether s ends with suffix, ASCII case-insensitively, under the same folding contract as HasPrefixFold. An empty suffix matches any s.

func IncrementIPRange 

func IncrementIPRange(ip net.IP)

IncrementIPRange Find available next IP address

func IndexAny2 added in v2.1.2 

func IndexAny2[S byteSeq](s S, a, b byte) int

IndexAny2 returns the index of the first occurrence in s of either a or b, or -1 if neither is present. On amd64 CPUs with AVX2, inputs of 32+ bytes dispatch to package simd instead.

func IndexAny3 added in v2.1.2 

func IndexAny3[S byteSeq](s S, a, b, c byte) int

IndexAny3 returns the index of the first occurrence in s of a, b, or c, or -1 if none is present. On amd64 CPUs with AVX2, inputs of 32+ bytes dispatch to package simd instead.

func IndexFold added in v2.1.2 

func IndexFold[S byteSeq](s S, needle string) int

IndexFold returns the index of the first ASCII case-insensitive occurrence of needle in s, or -1 if absent. An empty needle matches at index 0. Only 'A'..'Z'/'a'..'z' fold; every other byte (including >= 0x80) must match exactly, so e.g. "no\rcache" does NOT match the needle "no-cache". The needle is a plain string by design: call sites pass constant tokens, and a []byte needle would cost its callers a conversion either way.

func IndexNonQuotable added in v2.1.2 

func IndexNonQuotable[S byteSeq](s S) int

IndexNonQuotable returns the index of the first byte of s that cannot appear verbatim inside an RFC 9110 quoted-string — that is, a byte matching c == '\\' || c == '"' || (c < 0x20 && c != '\t') || c == 0x7f — or -1 if every byte is quotable. qdtext is HTAB / SP / %x21 / %x23-5B / %x5D-7E / obs-text, so HTAB and bytes >= 0x80 are quotable. Returning the index (rather than a bool) lets callers copy the clean prefix and start escaping exactly at the offending byte. Inputs of 8+ bytes finish with one overlapping word at n-8, shorter ones byte-wise.

func IsASCII added in v2.1.2 

func IsASCII[S byteSeq](s S) bool

IsASCII reports whether s contains only ASCII bytes (no byte >= 0x80). It ORs four words per iteration where possible (no index is needed, so detection can be deferred to one test per 32 bytes), then tests word-wise; inputs of 8+ bytes finish with one overlapping word at n-8, shorter ones byte-wise. On amd64 CPUs with AVX2, inputs of 32+ bytes dispatch to package simd instead.

func IsIPv4 

func IsIPv4(s string) bool

IsIPv4 works the same way as net.ParseIP, but without check for IPv6 case and without returning net.IP slice, whereby IsIPv4 makes no allocations.

func IsIPv6 

func IsIPv6(s string) bool

IsIPv6 works the same way as net.ParseIP, but without check for IPv4 case and without returning net.IP slice, whereby IsIPv6 makes no allocations.

func ParseFloat32
