Package hex implements hexadecimal encoding and decoding.
ErrLength reports an attempt to decode an odd-length input using Decode or DecodeString. The stream-based Decoder returns io.ErrUnexpectedEOF instead of ErrLength.
Decode decodes src into DecodedLen(len(src)) bytes, returning the actual number of bytes written to dst.
Decode expects that src contains only hexadecimal characters and that src has even length. If the input is malformed, Decode returns the number of bytes decoded before the error.
DecodeString returns the bytes represented by the hexadecimal string s.
DecodeString expects that src contains only hexadecimal characters and that src has even length. If the input is malformed, DecodeString returns the bytes decoded before the error.
DecodedLen returns the length of a decoding of x source bytes. Specifically, it returns x / 2.
Dump returns a string that contains a hex dump of the given data. The format of the hex dump matches the output of `hexdump -C` on the command line.
Dumper returns a WriteCloser that writes a hex dump of all written data to w. The format of the dump matches the output of `hexdump -C` on the command line.
Encode encodes src into EncodedLen(len(src)) bytes of dst. As a convenience, it returns the number of bytes written to dst, but this value is always EncodedLen(len(src)). Encode implements hexadecimal encoding.
EncodeToString returns the hexadecimal encoding of src.
EncodedLen returns the length of an encoding of n source bytes. Specifically, it returns n * 2.
NewDecoder returns an io.Reader that decodes hexadecimal characters from r. NewDecoder expects that r contain only an even number of hexadecimal characters.
NewEncoder returns an io.Writer that writes lowercase hexadecimal characters to w.
InvalidByteError values describe errors resulting from an invalid byte in a hex string.
