Formatting and shortening byte slices as hexadecimal strings
This crate provides wrappers for byte slices and lists of byte slices that implement the
standard formatting traits and print the bytes as a hexadecimal string, eliding from the middle
if the length would exceed the precision
format parameter.
use hex_fmt::{HexFmt, HexList};
assert_eq!("090a0b", &format!("{}", HexFmt(&[9u8, 10, 11])));
let nine_to_f = [9u8, 10, 11, 12, 13, 14, 15];
assert_eq!("090..0f", &format!("{:.7}", HexFmt(&nine_to_f)));
assert_eq!("090..e0f", &format!("{:.8}", HexFmt(&nine_to_f)));
assert_eq!("090a..0e0f", &format!("{}", HexFmt(&nine_to_f)));
assert_eq!("[4142, 4241]", &format!("{}", HexList(&[b"AB", b"BA"])));
