Trait EqFn

pub trait EqFn<C, T, E>
where
    C: ?Sized,
    T: ?Sized,
{
    // Required method
    fn eq(&self, cx: &mut C, key: &T) -> Result<bool, E>;
}

Trait used to implement custom equality implementations which are not solely based on traits.

Required Methods

fn eq(&self, cx: &mut C, key: &T) -> Result<bool, E>

Implementors

impl<T, C, K, V, E> EqFn<C, (K, V), E> for TupleFn<T, V>

where T: EqFn<C, K, E>, C: ?Sized,

impl<U, C, T, E> EqFn<C, T, E> for U

where U: Fn(&mut C, &T) -> Result<bool, E>, C: ?Sized, T: ?Sized,
