TryFrom and FromStr #1822
Description
Right now, it seems like a blanket TryFrom could be implemented for everything that implements FromStr:
impl<'a, T: FromStr> TryFrom<&'a str> for T {
type Err = <T as FromStr>::Err;
fn try_from(s: &'a s) -> Result<T, Self::Err> {
T::from_str(s)
}
}
This seems like something that should be reconciled. It'd be very confusing if anything implemented TryFrom<&'a str> and FromStr and didn't have the same implementation for both.
