Trait KeyedEq 

pub trait KeyedEq {
    type Key;

    // Required method
    fn different_keys<'l>(
        &'l self,
        other: &'l Self,
    ) -> SmallVec<[&'l Self::Key; 2]>;
}

Required Associated Types

type Key

Required Methods

fn different_keys<'l>(&'l self, other: &'l Self) -> SmallVec<[&'l Self::Key; 2]>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
