Trait Map 

pub trait Map<K, T> {
    // Required methods
    fn len(&self) -> usize;
    fn get(&self, key: &K) -> Option<&T>;
    fn set(&mut self, key: &K, value: T);
    fn map<F>(&mut self, f: F)
       where F: Fn(&K, T) -> T;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Required Methods

fn len(&self) -> usize

fn get(&self, key: &K) -> Option<&T>

fn set(&mut self, key: &K, value: T)

fn map<F>(&mut self, f: F)

where F: Fn(&K, T) -> T,

Provided Methods

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

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