hexlit

A zero-allocation no_std-compatible zero-cost way to convert hex-strings to byte-arrays at compile time.

To add to your Cargo.toml: toml hexlit = "0.5.2"

Example

```rust use hexlit::hex;

fn main() { const DATA: [u8; 4] = hex!("01020304"); asserteq!(DATA, [1, 2, 3, 4]); asserteq!(hex!("a1b2c3d4"), [0xA1, 0xB2, 0xC3, 0xD4]); asserteq!(hex!("E5 E6 90 92"), [0xE5, 0xE6, 0x90, 0x92]); asserteq!(hex!("0a0B0C0d"), [10, 11, 12, 13]); asserteq!(hex!(1a 0b 0C 0d), [0x1a, 11, 12, 13]); asserteq!(hex!(0F 03|0B|0C|0d), [15, 3, 11, 12, 13]); asserteq!(hex!(0A-0B-0C-0d), [10, 11, 12, 13]); } ```
