Struct ResourceRegistry 

pub struct ResourceRegistry { /* private fields */ }

Shared registry of GPU textures and shaders, with generation-checked handles and reference counting.

Slots are recycled via a free list when their reference count reaches zero. The generation counter prevents stale handles from aliasing new allocations.

Implementations

impl ResourceRegistry

pub fn new() -> Self

Construct an empty registry.

pub fn alloc_texture(&mut self, name: String) -> TextureHandle

Allocate a texture slot with an initial reference count of 1.

pub fn retain_texture(&mut self, h: TextureHandle) -> bool

Increment the reference count of h.

Returns false if the handle is stale (generation mismatch or out-of-bounds); returns true on success.

pub fn release_texture(&mut self, h: TextureHandle)

Decrement the reference count of h.

When the count reaches zero the slot’s generation is bumped and the slot is pushed onto the free list for reuse. Stale or already-freed handles are silently ignored.

pub fn get_texture(&self, h: TextureHandle) -> Option<&str>

Return the name associated with h, or None if stale.

pub fn alloc_shader(&mut self, name: String) -> ShaderHandle

Allocate a shader slot with an initial reference count of 1.

pub fn retain_shader(&mut self, h: ShaderHandle) -> bool

Increment the reference count of h.

Returns false if the handle is stale; returns true on success.

pub fn release_shader(&mut self, h: ShaderHandle)

Decrement the reference count of h.

When the count reaches zero the slot is freed and the generation is bumped. Stale handles are silently ignored.

pub fn get_shader(&self, h: ShaderHandle) -> Option<&str>

Return the name associated with h, or None if stale.

Trait Implementations

impl Default for ResourceRegistry

fn default() -> Self

Returns the “default value” for a type.
