Struct hex_display::Hex

pub struct Hex<'a>(pub &'a [u8]);

A wrapper type for &[u8] which implements Display by providing a hexdump

See HexDisplayExt for an easier method of constructing this type.

By default, it outputs a lower-case hexdump, but it outputs upper-case if provided with {:X} formatting option.

use hex_display::Hex;

assert_eq!(
    format!("{}", Hex(&[0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef])),
    "0123456789abcdef"
);
assert_eq!(
    format!("{:?}", Hex(&[0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef])),
    "0123456789abcdef"
);
assert_eq!(
    format!("{:X}", Hex(&[0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef])),
    "0123456789ABCDEF"
);
