stdx/bytes
Import path: github.com/InsideGallery/core/stdx/bytes
Overview
stdx/bytes provides byte, bit, little-endian, XOR, CRC, rotation, and padding helpers.
Main APIs
GetByteLSB,GetBitLSB,LSBBytesToInt, andLSBBitValuework with least-significant-byte ordering.LeftNibble,RightNibble, andUnsignedByteToIntextract byte parts and unsigned values.XORandXORAltreturn XORed byte slices.JamCRC32returns the little-endian IEEE CRC-32 with all bits inverted.RotateLeftandRotateRightrotate byte slices by the requested count.PadMessageToBlocksizepads non-aligned messages with0x80followed by zero bytes.
Usage
crc := bytesx.JamCRC32([]byte("123456789"))
rotated := bytesx.RotateLeft([]byte{1, 2, 3, 4}, 1)
value := bytesx.LSBBytesToInt([]byte{0x34, 0x12})
_ = crc
_ = rotated
_ = value
Notes
The helpers do not read configuration. Functions that return slices allocate new result slices except
PadMessageToBlocksize, which returns the original message when its length is already a multiple of the block
size.

Overview ¶
Package stdx is a legacy aggregate of byte, strings, hash, context, password, and slice helpers.
New helpers should live in the package that owns the concept. Existing exports remain for compatibility.
