Trait hecs_schedule::GenericWorld

pub trait GenericWorld {
    fn query<Q: Query + Subset>(&self) -> QueryBorrow<'_, Q>;
    fn query_one<Q: Query + Subset>(
        &self, 
        entity: Entity

        &self, 
        entity: Entity
    ) -> Result<Ref<'_, C>, ComponentError>;
}

Trait for allowing function to work on both World and SubWorld

Required methods

fn query<Q: Query + Subset>(&self) -> QueryBorrow<'_, Q>

Queries the world

fn query_one<Q: Query + Subset>(
    &self,
    entity: Entity
) -> Result<QueryOne<'_, Q>, NoSuchEntity>

Queries the world for a specific entity

fn get<C: Component>(
    &self,
    entity: Entity
) -> Result<Ref<'_, C>, ComponentError>

Get a single component for an entity Returns the contextual result since hecs-schedule is required to be imported anyway
