Struct TextureCache 

pub struct TextureCache { /* private fields */ }

Manages a collection of GPU textures (CPU-side stubs for Phase 2).

Implementations

impl TextureCache

pub fn new() -> Self

Create an empty texture cache.

pub fn insert(&mut self, desc: TextureDescriptor, data: Option<Vec<u8>>) -> u32

Insert a new texture, returning its unique id.

pub fn get(&self, id: u32) -> Option<&TextureEntry>

Retrieve a reference to a texture by id.

pub fn remove(&mut self, id: u32) -> bool

Remove a texture by id. Returns true if it was present.

pub fn count(&self) -> usize

Total number of entries (loaded or not).

pub fn loaded_count(&self) -> usize

Number of entries where loaded == true.

pub fn mark_loaded(&mut self, id: u32, data: Vec<u8>) -> bool

Supply pixel data for a previously-inserted placeholder texture. Returns false if the id is not found.

pub fn evict_all(&mut self)

Evict pixel data from all entries (streaming eviction), keeping descriptors.

pub fn total_memory_bytes(&self) -> usize

Sum of memory used by all loaded textures.

Trait Implementations

impl Default for TextureCache

fn default() -> Self

Returns the “default value” for a type.
