Trait Map 

pub trait Map<K, V> {
    // Required method
    fn insert(&mut self, key: K, value: V);
}

A trait for “map” types (such as HashMap) that you can collect into with an AggregateMap.

Implementations of this trait are provided for std maps, but if you have a custom map type you can implement this trait for it to be able to use it with AggregateMap.

Implementors of this trait will generally have a key of K, but a value of some collection type (like Vec or HashSet), which contains multiple values of type V.

Required Methods

fn insert(&mut self, key: K, value: V)

Insert one value into the collection contained at key.

Dyn Compatibility

This trait is dyn compatible.

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