Crate hex

  

This crate provides a fast conversion of byte arrays to hexadecimal strings, both at compile time, and at run time.

It aims to be a drop-in replacement for the hex crate, as well as extending the API with const-eval, a const-generics formatting buffer, similar to itoa’s, and more.

Version requirement: rustc 1.64+

Modules

serde

Hex encoding with serde.

traits

Modified from hex.

Structs

Buffer

A correctly sized stack allocation for the formatted bytes to be written into.

Enums

FromHexError

The error type for decoding a hex string into Vec<u8> or [u8; N].

Constants

HEX_CHARS_LOWER

The table of lowercase characters used for hex encoding.

HEX_CHARS_UPPER

The table of uppercase characters used for hex encoding.

HEX_DECODE_LUT

The lookup table of hex byte to value, used for hex decoding.

NIL

Represents an invalid value in the HEX_DECODE_LUT table.

Traits

FromHex

Types that can be decoded from a hex string.

ToHexDeprecated

Encoding values as hex string.

ToHexExt

Encoding values as hex string.
