# Trait bound Typemap
This crate offers typemaps that restrict a given type in their
trait and therefore offer additional trait implementations such as `Clone`.
## Usage
```rust
use trait_bound_typemap::{CloneTypeMap, TypeMapTrait, TypeMapKey};
#[derive(Clone)]
pub struct MyStruct {
a: u8,
b: String,
}
pub struct MyStructKey;
impl TypeMapKey for MyStructKey {
type Value = MyStruct;
}
fn main() {
let mut map = CloneTypeMap::new();
let value = MyStruct {a: 5, b: String::from("Hello World")};
map.insert::<MyStructKey>(value);
assert!(map.contains_key::<MyStructKey>());
}
```
