We can't name a specific error type in `PrimitiveNumber: FromStr` because it's different between floats and ints. However, we **can** refine that in `PrimitiveFloat` and `PrimitiveInteger` to specify their respective error types. Similarly, `PrimitiveInteger: TryFrom<_>` is not specific because the error could be `Infallible` or `TryFromIntError`. In the cases of `PrimitiveSigned: TryFrom<i8>` and `PrimitiveUnsigned: TryFrom<u8>` though, we do know they are always `Infallible` -- which is implied by their respective `From`, but needs to be explicit.
