    fn get(self, entity: EntityId) -> Result<Self::Out, MissingComponent>;

    fn fast_get(
        self, 
        entity: EntityId
    ) -> Result<Self::FastOut, MissingComponent>;

Required methods

fn get(self, entity: EntityId) -> Result<Self::Out, MissingComponent>[src]

Retrieve components of entity.

Multiple components can be queried at the same time using a tuple.

Example:

use shipyard::{Get, View, World};

let mut world = World::new();

let entity = world.add_entity((0usize, 1u32));

let (usizes, u32s) = world.borrow::<(View<usize>, View<u32>)>().unwrap();
assert_eq!((&usizes, &u32s).get(entity), Ok((&0, &1)));

fn fast_get(self, entity: EntityId) -> Result<Self::FastOut, MissingComponent>[src]

Retrieve components of entity without fine modification tracking.

Multiple components can be queried at the same time using a tuple.

Example:

use shipyard::{Get, View, World};

let mut world = World::new();

let entity = world.add_entity((0usize, 1u32));

let (usizes, u32s) = world.borrow::<(View<usize>, View<u32>)>().unwrap();
assert_eq!((&usizes, &u32s).fast_get(entity), Ok((&0, &1)));
