Struct GCDynamicReusableAllocator 

pub struct GCDynamicReusableAllocator<T: Default> {
    object_memory: RwLock<Vec<GCArc<T>>>,
    empty_indexes: Arc<RwLock<VecDeque<usize>>>,
}

A dynamic reusable memory allocator which uses a RwLock<VecDeque> to store the empty available memory locations. It will attempt to reuse any memory blocks already allocated, otherwise it will do an additional allocation.

Uses a VecDeque to keep track of the empty indexes and all memory blocks have a reference to it.

Fields

object_memory: RwLock<Vec<GCArc<T>>>

empty_indexes: Arc<RwLock<VecDeque<usize>>>

Implementations

impl<T: Default> DynamicReusableAllocator<T>

pub fn new(size: usize) -> DynamicReusableAllocator<T>

pub unsafe fn clear(&self)

Clears the memory allocator and resets it to the initial state The caller has to ensure that there are no more references to the memory blocks. This function should only be used for testing purposes.

Safety

This will clear all the memory blocks available, if there are still references to them, it is considered undefined behavior.

Trait Implementations

impl<T: Default + 'static> GCAllocator<T> for DynamicReusableAllocator<T>

fn add(&self, element: T) -> GCArc<T>

Adds a new element to the allocator, if the allocator is full it will allocate a new block of memory.

fn allocated_count(&self) -> usize

Returns the number of allocated elements

fn available_allocated_count(&self) -> usize

Returns the number of available allocated elements
