Module resource 

Generation-checked resource handles and reference-counted registry.

Resources (textures, shaders) are identified by TextureHandle and ShaderHandle — lightweight generation-checked tokens. The ResourceRegistry tracks reference counts and recycles slots so the same index can be safely reused without stale-handle confusion.

RAII wrappers (TextureGuard, ShaderGuard) automatically decrement the reference count when dropped.

Structs

ResourceId

A generation-checked resource identifier.

ResourceRegistry

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

ShaderGuard

RAII wrapper that releases a ShaderHandle when dropped.

ShaderHandle

An opaque handle to a GPU shader resource.

TextureGuard

RAII wrapper that releases a TextureHandle when dropped.

TextureHandle

An opaque handle to a GPU texture resource.
