Macro bytesmin

bytesmin!() { /* proc-macro */ }

Bytesmin converts literals into an array of bytes of minimal size to capture the value.

Currently supports only integer literals of unbounded size.

Leading zeroes on integer literals are discarded and not preserved. The generated byte slice is the minimal bytes required to capture the literal provided.

To preserve leading zeros, use bytes!.

Examples

let bytes = bytes_lit::bytesmin!(1);
assert_eq!(bytes, [1]);

let bytes = bytes_lit::bytesmin!(9);
assert_eq!(bytes, [9]);

let bytes = bytes_lit::bytesmin!(0xfded3f55dec47250a52a8c0bb7038e72fa6ffaae33562f77cd2b629ef7fd424d);
assert_eq!(bytes, [
    253, 237, 63, 85, 222, 196, 114, 80, 165, 42, 140, 11, 183, 3, 142, 114,
    250, 111, 250, 174, 51, 86, 47, 119, 205, 43, 98, 158, 247, 253, 66, 77,
