Struct dces::system::SystemStore

pub struct SystemStore<E, C, Ctx> where
    E: EntityStore,
    C: ComponentStore,  {
    pub priorities: BTreeMap<i32, Vec<u32>>,
    // some fields omitted
}

The SystemStore represents the main system storage.

Fields

priorities: BTreeMap<i32, Vec<u32>>

Priorities of the systems.

Implementations

impl<E, C, Ctx> SystemStore<E, C, Ctx> where
    E: EntityStore,
    C: ComponentStore, 

pub fn new() -> Self

Creates a new system store with default values.

pub fn register_init_system(&mut self, init_system: impl System<E, C, Ctx>)

Registers the init system.

pub fn register_cleanup_system(
    &mut self,
    cleanup_system: impl System<E, C, Ctx>
)

Registers the cleanup system.

pub fn register_system(
    &mut self,
    system: impl System<E, C, Ctx>,
    system_id: u32
)

Registers a new system.

pub fn remove_system(&mut self, system_id: u32)

Removes a system from the storage.

pub fn register_priority(&mut self, priority: Priority, system_id: u32)

Register a priority for the system with the given system_id.

pub fn borrow_entity_system(
    &self,
    entity_system_id: u32
) -> Result<&EntitySystem<E, C, Ctx>, NotFound>

Returns a reference of a entity system. If the entity system does not exists NotFound will be returned.

pub fn borrow_init_system(&self) -> &Option<EntitySystem<E, C, Ctx>>

Returns a reference of the init entity system. If the init entity system does not exists None will be returned.

pub fn borrow_cleanup_system(&self) -> &Option<EntitySystem<E, C, Ctx>>

Returns a reference of the cleanup entity system. If the init entity system does not exists None will be returned.

Trait Implementations

impl<E: Default, C: Default, Ctx: Default> Default for SystemStore<E, C, Ctx> where
    E: EntityStore,
    C: ComponentStore, 

fn default() -> SystemStore<E, C, Ctx>

Returns the "default value" for a type.
