Struct dces::system::EntitySystemManager

pub struct EntitySystemManager<T> where
    T: EntityContainer,  {
    pub priorities: BTreeMap<i32, Vec<u32>>,
    // some fields omitted
}

The EntitySystemManager represents the main system storage.

Fields

priorities: BTreeMap<i32, Vec<u32>>

Priorities of the systems.

Methods

impl<T> EntitySystemManager<T> where     T: EntityContainer,

pub fn new() -> Self

Creates a new entity system manager with default values.

pub fn register_init_system(     &mut self,     init_system: impl System<T> )

Registers the init system.

pub fn register_cleanup_system(     &mut self,     cleanup_system: impl System<T> )

Registers the cleanup system.

pub fn register_system(     &mut self,     system: impl System<T>,     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<T>, 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<T>>

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<T>>

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