Constants

const (
	DiKB int64 = 1 << 10
	DiMB int64 = DiKB << 10
	DiGB int64 = DiMB << 10
)

Variables

var (
	// our memory is much cheaper than systems,
	// so we can be more aggressive than `append`.
	SliceExtendRatio = 2.5

	BugfixClearPointerInMem = true
	BugfixCorruptOtherMem   = true
)

Functions

func Append

func Append[T any](ac *Allocator, s []T, elems ...T) []T

Append append slice

func New

func New[T any](ac *Allocator) (r *T)

New 分配新对象

func NewSlice

func NewSlice[T any](ac *Allocator, len, cap int) (r []T)

NewSlice does not zero the slice automatically, this is OK with most cases and can improve the performance. zero it yourself for your need.
