Functions

decode

Decodes a hex string into a vector of bytes.

decode_len

Returns the decoded length for a given hex string length.

decode_mut

Decodes a hex string in-place, writing to a destination buffer.

decode_n

Decodes hex at compile time with validation.

encode

Encodes bytes to lowercase hex, returning an Encoder.

encode_len

Returns the exact encoded length for a given source byte length.

encode_mut

Encodes bytes to lowercase hex into a flat byte buffer.

encode_n

Encodes bytes to lowercase hex at compile time.

parse_byte

Parses two hex characters into a byte.

parse_nibble

Safely parses a hex character into a nibble (0-15).

skip_0x

Skips the 0x or 0X prefix from a byte slice if present.

skip_leading_zeros

Skips leading zero characters from a byte slice.

Type Aliases

CharEncoder

Iterator that encodes bytes as hex characters (char type).
