pub struct GpuBufferPool { /* private fields */ }

A simple pool that allocates and recycles GpuBuffer instances.

Implementations

impl GpuBufferPool

pub fn new() -> Self

Creates a new, empty buffer pool.

pub fn allocate(&mut self, usage: BufferUsage, size: usize) -> GpuBuffer

Allocates a buffer of the given usage and size.

If a compatible free buffer exists it is reused; otherwise a new one is created.

pub fn release(&mut self, buf: GpuBuffer)

Returns a buffer to the pool for future reuse.

pub fn total_allocated(&self) -> usize

Returns the total number of bytes currently allocated across all active and free buffers.

pub fn active_count(&self) -> usize

Returns the number of active (in-use) buffers.

pub fn free_count(&self) -> usize

Returns the number of buffers waiting in the free list.
