Trait Policy

pub trait Policy {
    type K;
    type V;

    // Required methods
    fn insert(map: &mut DynMap, key: Self::K, value: Self::V);
    fn get<'a>(map: &'a DynMap, key: &Self::K) -> Option<&'a Self::V>;
    fn is_empty(map: &DynMap) -> bool;
}

Required Associated Types

type K

type V

Required Methods

fn insert(map: &mut DynMap, key: Self::K, value: Self::V)

fn get<'a>(map: &'a DynMap, key: &Self::K) -> Option<&'a Self::V>

fn is_empty(map: &DynMap) -> bool

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.
