Implementations

impl VulkanSuballocator

pub fn new() -> Self

pub fn allocate( &mut self, device: &Device, size: u64, alignment: u64, memory_type_index: u32, is_host_visible: bool, is_coherent: bool, allocation_type: AllocationType, ) -> Result<AllocationResult, HalError>

pub fn free(&mut self, block_id: usize, offset: u64, size: u64, device: &Device)

pub fn trim(&mut self, device: &Device) -> usize

Reclaims ALL completely empty blocks, releasing their GPU and host memory back to Vulkan. Returns the number of reclaimed blocks.

pub fn block_count(&self) -> usize

Returns the total number of blocks currently held by the suballocator.

pub fn empty_block_count(&self) -> usize

Returns the number of completely empty blocks currently held by the suballocator.

pub fn total_capacity_bytes(&self) -> u64

Returns the total capacity in bytes across all managed blocks.

pub fn total_free_bytes(&self) -> u64

Returns the total available free bytes across all managed blocks.

pub fn destroy(&mut self, device: &Device)
