Crate trait_bound_typemap

Trait bound Typemap

This crate offers typemaps that restrict a given type in their trait and therefore offer additional trait implementations such as Clone and PartialEq.

Usage

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>());
}

Structs

CloneTypeMap

A typemap that can be cloned restricting all inner types to implement std::clone::Clone as well.

PartialEqTypeMap

A typemap that provides a PartialEq implementation

TypeMap

A typemap that can store any type (implementing std::any::Any).

Traits

TypeMapKey

A trait that allows using the object implementing it to be used as a type key.

TypeMapTrait

A trait implemented by all typemaps that provides all basic typemap functions
