Enum Encoding 

#[repr(u8)]
pub enum Encoding {
    Lowercase = 0,
    Uppercase = 1,
}

Character set for hex encoding (uppercase or lowercase).

Variants

Lowercase = 0

Lowercase hex digits (a-f)

Uppercase = 1

Uppercase hex digits (A-F)

Implementations

impl Encoding

pub const fn encode_nibble(self, nibble: u8) -> u8

Converts a nibble (0-15) to a hex character using branchless arithmetic.

Examples

use omp_core::hex::{LOWER, UPPER};
assert_eq!(LOWER.encode_nibble(10), b'a');
assert_eq!(UPPER.encode_nibble(15), b'F');

pub const fn encode_mut(self, src: &[u8], dst: &mut [u8]) -> usize

Encodes bytes to hex into a flat byte buffer.

Writes ASCII hex characters to dst and returns the number of bytes written. The output length is min(dst.len(), 2 * src.len()).

Examples

use omp_core::hex;
let mut buf = [0u8; 10];
let n = hex::LOWER.encode_mut(b"Hello", &mut buf);
assert_eq!(n, 10);
assert_eq!(&buf, b"48656c6c6f");

pub const fn encode_byte(self, byte: u8) -> [u8; 2]

Encodes a single byte to a hex pair.

Examples

use omp_core::hex::{LOWER, UPPER};
assert_eq!(LOWER.encode_byte(0x48), *b"48");
assert_eq!(UPPER.encode_byte(0xff), *b"FF");

pub const fn encode_n<const N: usize>(self, src: &[u8; N]) -> ArrayStr<N>

Encodes a byte array to a hex string at compile time.

pub const fn lut(self) -> &'static [u16; 256]

Returns the lookup table for this charset.

Trait Implementations

impl Eq for Encoding

impl Ord for Encoding

fn cmp(&self, other: &Encoding) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Encoding

fn partial_cmp(&self, other: &Encoding) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
