pub fn to_signed_with_radix<I: MinNumTraits>(
bytes: &[u8],
radix: u32,
) -> Result<I, ParseIntegerError>
Expand description
Converts a byte slice in a given base to an integer.
Like to_unsigned_with_radix
, but numbers may optionally start with a sign
(-
or +
).
§Errors
Returns ParseIntegerError
for any of the following conditions:
bytes
has no digits- not all characters of
bytes
are0-9
,a-z
,A-Z
, excluding an optional leading sign - not all characters refer to digits in the given
radix
, excluding an optional leading sign - the number overflows or underflows
I
§Panics
Panics if radix
is not in the range 2..=36
(or in the pathological
case that there is no representation of radix
in I
).
§Examples
assert_eq!(Ok(10), to_signed_with_radix(b"a", 16));
assert_eq!(Ok(10), to_signed_with_radix(b"+a", 16));
assert_eq!(Ok(-42), to_signed_with_radix(b"-101010", 2));
