numeric_constant_traits

Traits for generic numeric constants

Like the traits Zero and One from the num crate, but for all natural numbers up to and including 100. Allows doing generic arithmetic without having to do casts.

Without this crate you'd need to do something like:

2u8.into() * 3u8.into() + 4u8.into()

Which is okay, but obfuscates a bit what the intent is.

With this crate you can do something like this:

T::two() * T::three() + T::four()

The traits are implemented for all standard numeric types, as well as a blanket implementation for num::Complex<T>, where T is any of the standar numeric types.
