Struct jazz::object_pool::ObjectPool

pub struct ObjectPool { /* private fields */ }

An object pool that provides the backing object storage for executors.

Implementations

impl ObjectPool

pub fn new() -> ObjectPool

pub fn allocate(&mut self, inner: Box<dyn Object>) -> usize

Pins an object to the pool.

pub fn get<'a>(&self, id: usize) -> ObjectHandle<'a>

Gets a handle to the object at id.

The handle can be passed around safely and the underlying object will not be garbage collected until all handles to it are released.

If the object pool gets destroyed before all handles are dropped, the process will be aborted because of memory unsafety introduced by reference invalidation.

pub fn get_direct(&self, id: usize) -> &dyn Object

Gets a direct reference to the object at id.

pub fn get_direct_typed<T: 'static>(&self, id: usize) -> Option<&T>

Gets a direct typed reference to the object at id. If downcast fails, None is returned.

pub fn must_get_direct_typed<T: 'static>(&self, id: usize) -> &T

Gets a direct reference to the object at id. If downcast fails, this raises a RuntimeError.

pub fn get_typed<'a, T: 'static>(
    &self,
    id: usize
) -> Option<TypedObjectHandle<'a, T>>

Gets a typed object handle to the object at id. If downcast fails, None is returned.

pub fn must_get_typed<'a, T: 'static>(
    &self,
    id: usize
) -> TypedObjectHandle<'a, T>

Gets a typed object handle to the object at id. If downcast fails, this raises a RuntimeError.

pub fn get_static_root<'a>(&self) -> TypedObjectHandle<'a, StaticRoot>

pub fn get_direct_static_root(&self) -> &StaticRoot

pub fn get_alloc_count(&self) -> usize

pub fn reset_alloc_count(&mut self)

Trait Implementations

impl Drop for ObjectPool

fn drop(&mut self)

Executes the destructor for this type.
