pub struct TexturePool { /* private fields */ }

A pool of GPU textures backed by a fixed memory budget

Implementations

impl TexturePool

pub fn new(max_gb: f64) -> Self

Create a pool with a budget of max_gb gigabytes

pub fn allocate(&mut self, desc: TextureDescriptor) -> Option<usize>

Allocate a texture in the pool

Returns Some(handle) on success, or None if the budget is exceeded.

pub fn free(&mut self, id: usize)

Free a texture by handle

pub fn utilization(&self) -> f64

Utilisation in [0.0, 1.0]

pub fn live_count(&self) -> usize

Number of live (allocated) textures

pub fn allocated_bytes(&self) -> usize

Currently allocated bytes

pub fn max_bytes(&self) -> usize

Pool capacity in bytes
