Functions

func Alloc

func Alloc(size int) []byte

Alloc a slice of bytes with the given size. Sizes till MaxSize are supported, for larger sizes nil will be returned. The slices are taken from sync.Pool caches sized to the nearest power of two and truncated to the size supplied. This function may be called concurrently.

func Free

func Free(bs []byte)

Free a byte slice allocated by Alloc. The argument may be shorted from the original allocation, it is reset to len = cap. This function may be called concurrently.
