[−][src]Function zeros::bytes_to_hex
pub fn bytes_to_hex<B>(bytes: B) -> String where
B: AsRef<[u8]>,
Formats a byte slice as a hexadecimal string, in lower-case
This function uses HEX_STRS
, which (at the time) was faster than format!("{:02x}", ...)
.
Examples
assert_eq!(zeros::bytes_to_hex( &[202, 254]), "cafe"); assert_eq!(zeros::bytes_to_hex(&[192, 255, 238]), "c0ffee");
