Trait Cache 

pub trait Cache<I, O> {
    // Required method
    fn find<Q>(&self, q: &Q) -> O
       where Q: Eq + Hash + ToOwned<Owned = I> + ?Sized,
             I: Borrow<Q>;
}

A cache that can be polled for a value with its borrowed form.

Required Methods

fn find<Q>(&self, q: &Q) -> O

where Q: Eq + Hash + ToOwned<Owned = I> + ?Sized, I: Borrow<Q>,

Obtain the return value of the function for the owned version of this input.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
