Derive Macro Round 

#[derive(Round)]
{
    // Attributes available to this derive:
    #[derive_bound]
}

Round derive macro. for each method, the derive implementation maps each field using the method.

Generics

For types with generic parameters, Round will be implemented with no additional trait-bounds.

To add bounds to the derive, use the derive_bound attribute which follows this syntax: #[derive_bound(<trait-ident>; <where-predicate>, ...)].

Example

use newnum::*;

#[derive(Round)]
#[derive_bound(Round; T: Round)]
struct Fun<T>(T);
