#[implement]

Implement a trait for given enum or struct. The trait should be defined with target attribute.

Example

use newer_type::implement;
use newer_type::traits::{Extend, PartialEq};

#[implement(Extend<usize>)]
struct Example1(Vec<usize>);

#[implement(Extend<T>)]
struct Example2<T>(Vec<T>);

#[implement(for<T> PartialEq<T>)]
struct Example3(String);

#[implement(for<T: std::fmt::Debug> PartialEq<T>)]
struct Example4<U>(U);
