DeallocationStage

bevy::render::slab_allocator

Struct DeallocationStage 

Source 
pub struct DeallocationStage<'a, I>
where
    I: SlabItem,
{
    pub allocator: &'a mut SlabAllocator<I>,
    /* private fields */
}
Expand description

An object that enables batched deallocation.

To free objects from a SlabAllocator, call SlabAllocator::stage_deallocation to create a DeallocationStage, call Self::free to deallocate objects, and finally call Self::commit. You must call Self::commit in order to ensure that newly-empty slabs are deallocated.

Fields§

§allocator: &'a mut SlabAllocator<I>

The allocator in which objects are to be freed.

Implementations§

Source§

impl<'a, I> DeallocationStage<'a, I>
where I: SlabItem,

Source

pub fn free(&mut self, key: &<I as SlabItem>::Key)

Schedules a free operation for the allocation with the given key.

The key must correspond to a live allocation. An error will be emitted to the log otherwise.

Source

pub fn commit(self)

Performs all the free operations.

You must call this method if you called Self::free.
