Implement TryFrom<char> for usize. by bjoernager · Pull Request #146792 · rust-lang/rust (original) (raw)

Feature gate: usize_try_from_char.

This PR implements TryFrom<char> for usize.

usize is currently the only, unsigned, integral, type to not implement TryFrom<char>. Technically, this conversion is trivial and can already be expressed with some indirection.

I think it useful to be able to describe this set of types with this interface.
