Trait Implementations

impl<S: Clone + ?Sized, T: Clone + ?Sized + PartialEq<T>, F: Clone + Fn(&S) -> T> Clone for EqBy<S, T, F>

fn clone(&self) -> EqBy<S, T, F>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S: Copy + ?Sized, T: Copy + ?Sized + PartialEq<T>, F: Copy + Fn(&S) -> T> Copy for EqBy<S, T, F>

impl<S: Debug + ?Sized, T: Debug + ?Sized + PartialEq<T>, F: Debug + Fn(&S) -> T> Debug for EqBy<S, T, F>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<S, T, F> EqClass<S> for EqBy<S, T, F> where
    S: ?Sized,
    T: PartialEq<T>,
    F: Fn(&S) -> T, 

fn eq(&self, left: &S, right: &S) -> bool

This method tests for left and right values to be equal.

fn and<N>(self, next: N) -> BothEq<T, Self, N> where
    Self: Sized,
    N: EqClass<T>, 

This method returns an EqClass which is further refining the semantics of self.
