Golang standard library: bytes package – byte slice byte array convenient operation
2.2 bytes – byte slice convenient operation This package defines some convenience operations for manipulating byte slices. Because strings can be represented as []byte, the functions and methods defined by the bytes package are very similar to the strings package, so the explanation will be similar to the strings package and can even be referred […]
