newnum

The newnum Rust crate is an alternative to the num crate that splits the Rust number API and hierarchy into traits, with a cleaner design than num.

The design of this crate follows these rules:

• the Num trait isn't restricted to primitives, or to types that can represent specific common values (0, 1...).

• the Prim, SignedPrim, UnsignedPrim, Int, UInt, SInt, and Float traits are restricted to primitives, but allow non std types to implement them as long as they follow primitive restrictions.

• API traits (Round, Root, Trig...) aren't restricted to Num and are designed for non number support, for example <Angle as Trig>::Output = Ratio.

Development State

The crate is already very usable but makes breaking changes every version to improve the design.
