func Clone ¶ added in v2.240.0

func Clone(b []byte) []byte

Clone returns a copy of b.

This is a thin wrapper around bytes.Clone. Unlike helpers that may return subslices, Clone always allocates a new slice (unless b is nil, in which case it returns nil).

func NewBuffer ¶

func NewBuffer(buf []byte) *bytes.Buffer

NewBuffer returns a new Buffer initialized with buf's contents.

This is a thin wrapper around bytes.NewBuffer. The returned buffer uses buf as its initial contents; subsequent writes may grow the buffer.

func NewBufferString ¶

func NewBufferString(s string) *bytes.Buffer

NewBufferString returns a new Buffer initialized with the contents of s.

This is a thin wrapper around bytes.NewBufferString.

func NewReader ¶

func NewReader(b []byte) *bytes.Reader

NewReader returns a new bytes.Reader reading from b.

This is a thin wrapper around bytes.NewReader. The returned reader reads from b without copying.

func String ¶

func String(b []byte) string

String converts b to a string without copying.

Safety and lifetime ¶

The returned string aliases the memory backing b. That means:

• You MUST NOT modify the contents of b after calling String(b).
• The returned string is only valid while b remains alive (reachable) and its backing array is not reused.

Violating these constraints can lead to surprising behavior, data races, or memory safety issues. Use this helper only when you control the lifecycle of b and need to avoid an allocation. If you need an owning copy, use `string(b)` instead.

func TrimSpace ¶

func TrimSpace(s []byte) []byte

TrimSpace returns a subslice of s with all leading and trailing white space removed.

This is a thin wrapper around bytes.TrimSpace. The returned slice may refer to the same underlying array as s.
