[−][src]Trait specs::storage::GenericWriteStorage

pub trait GenericWriteStorage {
    type Component: Component;
    fn get_mut(&mut self, entity: Entity) -> Option<&mut Self::Component>;

    fn get_mut_or_default(
        &mut self,

Required methods

fn get_mut(&mut self, entity: Entity) -> Option<&mut Self::Component>

Get mutable access to an Entitys component

fn get_mut_or_default(&mut self, entity: Entity) -> Option<&mut Self::Component> where
    Self::Component: Default, 

Get mutable access to an Entitys component. If the component does not exist, it is automatically created using Default::default().

Returns None if the entity is dead.

fn insert(
    &mut self,
    entity: Entity,
    comp: Self::Component
) -> InsertResult<Self::Component>

Insert a component for an Entity

fn remove(&mut self, entity: Entity)

Remove the component for an Entity

fn _private() -> Seal

Private function to seal the trait
