Function to_unsigned

source 
pub fn to_unsigned<I: MinNumTraits>(
    bytes: &[u8],
) -> Result<I, ParseIntegerError>
Expand description

Converts a byte slice to an 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
  • the number overflows I

§Panics

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

§Examples

assert_eq!(Ok(12345), to_unsigned(b"12345"));
assert!(to_unsigned::<u8>(b"+1").is_err()); // only btoi allows signs
assert!(to_unsigned::<u8>(b"256").is_err()); // overflow
