Function extprim::traits::parse_rust_int_lit
[−]
[src]
pub fn parse_rust_int_lit<T: Num>(
s: &str,
is_negative: bool
) -> Result<T, T::FromStrRadixErr>
Parses a Rust integer literal into an actual integral type.
If is_negative
is true, a negative sign will be added to the string before the conversion.
