Crate ttmap[−][src]
Expand description
Trivial type-map implementation
Implementation uses type erased values with type as index.
Due to limitation of TypeId
only types without non-static references are supported. (in future it can be changed)
Hash implementation
The map uses simplified Hasher
that relies on fact that TypeId
produces unique values only.
In fact there is no hashing under hood, and type’s id is returned as it is.
Usage
use ttmap::TypeMap;
let mut map = TypeMap::new();
map.insert("string");
assert_eq!(*map.get::<&'static str>().unwrap(), "string");
map.insert(1u8);
assert_eq!(*map.get::<u8>().unwrap(), 1);
assert_eq!(map.get_or_default::<String>(), "");
Structs
Type-safe store, indexed by types.
