Trait dactyl::traits::HexToUnsigned

pub trait HexToUnsigned: Sized {
    // Required method
    fn htou(hex: &[u8]) -> Option<Self>;
}

Hex (Bytes) to Unsigned.

This trait exposes the method htou which converts Hex byte slices to proper, unsigned integers. It works just like u*::from_str_radix, but faster, particularly for u64 and u128.

Decoding is case-insensitive and padding-agnostic; slice lengths may be anything between 1..=std::mem::size_of::<Self>()*2.

Invalid slices, overflows, etc., will result in None being returned.

For signed integers, see HexToSigned.

Examples

use dactyl::traits::HexToUnsigned;

assert_eq!(u8::htou(b"d"), Some(13));
assert_eq!(u8::htou(b"D"), Some(13));
assert_eq!(u8::htou(b"0d"), Some(13));
assert_eq!(u8::htou(b"0D"), Some(13));

Required Methods

fn htou(hex: &[u8]) -> Option<Self>
