TypeMap

A typesafe store keyed by types and containing different types of values.

Documentation

It provides functionality similar to AnyMap, but is more flexible because it allows for key-value pairs, rather than enforcing that keys and values are the same type.

Key-value associations are defined through the

Key

TypeMap

Example

extern crate typemap;
use typemap::{TypeMap, Key};

struct KeyType;
#[derive(Debug, PartialEq)]
struct Value(i32);
impl Key for KeyType { type Value = Value; }
#[test] fn test_pairing() {
    let mut map = TypeMap::new();
    map.insert::(Value(42));
    assert_eq!(*map.get::().unwrap(), Value(42));
}
