Overview ¶
Package simd provides performance-optimized string operations using manual loop unrolling (processing 16 bytes per iteration). Despite the package name, these are NOT hardware SIMD/vector instructions — they are manually unrolled scalar loops that improve performance by reducing branch overhead and enabling better CPU pipelining. The Go compiler may auto-vectorize some patterns, but correctness does not depend on hardware SIMD support.

Functions ¶
func ContainsAny ¶
ContainsAny checks if string contains any of the substrings
func ContainsWord ¶
ContainsWord checks if string contains word (space-delimited)
func FastContains ¶
FastContains checks if string contains substring (optimized for small patterns)
func FastCountBytes ¶
FastCountBytes counts bytes using SIMD-optimized loop
func FastHasANSI ¶
FastHasANSI checks for ANSI sequences using SIMD-friendly loop
func SplitWords ¶
SplitWords splits string into words (optimized)
Types ¶
type CPUFeatures ¶
CPUFeatures holds detected CPU capabilities
type Dispatcher ¶
type Dispatcher struct {
// contains filtered or unexported fields
}
Dispatcher selects optimal SIMD implementation
func (*Dispatcher) EntropyFilter ¶
func (d *Dispatcher) EntropyFilter(data []float64) float64
