Crate const_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.

Functions

check

Returns true if the input is a valid hex string and can be decoded successfully.

check_raw

Returns true if the input is a valid hex string.

const_check

Returns true if the input is a valid hex string and can be decoded successfully.

const_check_raw

Returns true if the input is a valid hex string.

const_decode_to_array

Decode a hex string into a fixed-length byte-array.

const_encode

Encodes input as a hex string into a Buffer.

decodealloc

Decodes a hex string into raw bytes.

decode_to_array

Decode a hex string into a fixed-length byte-array.

decode_to_slice

Decode a hex string into a mutable bytes slice.

display

Returns a value that can be formatted using the fmt traits.

encodealloc

Encodes data as a hex string using lowercase characters.

encode_prefixedalloc

Encodes data as a prefixed hex string using lowercase characters.

encode_to_slice

Encodes input as a hex string using lowercase characters into a mutable slice of bytes output.

encode_to_slice_upper

Encodes input as a hex string using uppercase characters into a mutable slice of bytes output.

encode_to_str

Encodes input as a hex string using lowercase characters into a mutable slice of bytes output. Returns the slice to output reinterpreted as str.

encode_to_str_upper

Encodes input as a hex string using uppercase characters into a mutable slice of bytes output. Returns the slice to output reinterpreted as str.

encode_upperalloc

Encodes data as a hex string using uppercase characters.

encode_upper_prefixedalloc

Encodes data as a prefixed hex string using uppercase characters.
