Trait NestedHashMapExtensions 

pub trait NestedHashMapExtensions<K, K2, V> {
    // Required method
    fn insert_into_nested(
        &mut self,
        outer_key: K,
        inner_key: K2,
        inner_value: V,
    );
}

Required Methods

fn insert_into_nested(&mut self, outer_key: K, inner_key: K2, inner_value: V)

For use with a hashmap within a hashmap, takes an outer and inner key, and an inner value

1. if the outer key exists with and inner hashmap the key-value pair is inserted to the existing hashmap.
2. a new inner hashmap is created with the key-value pair if the outer key does not exist.

Dyn Compatibility

This trait is dyn compatible.

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