import "crypto/internal/alias"

Package alias implements memory aliasing tests. This code also exists as golang.org/x/crypto/internal/alias.

Index ¶

• func AnyOverlap(x, y []byte) bool
• func InexactOverlap(x, y []byte) bool

Functions ¶

func AnyOverlap ¶

func AnyOverlap(x, y []byte) bool

AnyOverlap reports whether x and y share memory at any (not necessarily corresponding) index. The memory beyond the slice length is ignored.

func InexactOverlap ¶

func InexactOverlap(x, y []byte) bool

InexactOverlap reports whether x and y share memory at any non-corresponding index. The memory beyond the slice length is ignored. Note that x and y can have different lengths and still not have any inexact overlap.

InexactOverlap can be used to implement the requirements of the crypto/cipher AEAD, Block, BlockMode and Stream interfaces.
