Function btou_saturating

Source 
pub fn btou_saturating<I>(bytes: &[u8]) -> Result<I, ParseIntegerError>
where
    I: FromPrimitive + Zero + CheckedMul + Saturating + Bounded,
Expand description

Converts a byte slice to the closest possible integer. Signs are not allowed.

§Errors

Returns ParseIntegerError for any of the following conditions:

  • bytes is empty
  • not all characters of bytes are 0-9

§Panics

Panics in the pathological case that there is no representation of 10 in I.

§Examples

assert_eq!(Ok(65535), btou_saturating::<u16>(b"65535"));
assert_eq!(Ok(65535), btou_saturating::<u16>(b"65536")); // u16 saturated
assert_eq!(Ok(65535), btou_saturating::<u16>(b"65537")); // u16 saturated
