Crate rs_ecs[−][src]
Expand description
A reasonably simple entity component system (ECS).
The design is based on hecs but it is not thread-safe and has a significantly reduced API surface.
Example
let mut world = World::new();
let entity = world.alloc();
world.insert(entity, (42_u32, true));
let entity = world.alloc();
world.insert(entity, (23_u32, "hello".to_string()));
for number in Query::<&u32>::new().borrow(&world).iter() {
println!("{}", number);
}
for (_entity, number, string) in Query::<(&Entity, &u32, &String)>::new().borrow(&world).iter() {
println!("{}, {}", string, number);
}
Structs
An immutable borrow of a component.
A mutable borrow of a component.
An opaque entity identifier.
A query specification to indicate which entities match the inner query, but without borrowing any components.
Query to get an iterator over all entities with a certain combination of components.
Used to iterate through the entities which match a certain Query in parallel.
An immutable borrow of a resource.
A mutable borrow of a resource.
A type map for holding resources.
A query specification to iterate over entities with a certain component, but without borrowing that component.
A query specification to iterate over entities without a certain component.
The world storing entities and their components.
Traits
Type level specification of a query for a certain set of components.
