Module backend 

Core GPU backend abstraction: enums, handle types, capability queries, and the BackendContext trait that every concrete backend implements.

Structs

BackendCapabilities

Capabilities of the current backend.

BindGroupLayoutDesc

Describes one bind-group layout.

BindGroupLayoutEntry

One entry within a bind-group layout.

BufferHandle

Opaque handle to a GPU buffer.

BufferUsage

Buffer usage flags (combinable via bitwise OR on the underlying bits).

ComputePipelineHandle

Opaque handle to a compute pipeline.

OpenGLContext

OpenGL backend context. In a headless / test environment this behaves identically to SoftwareContext since we don’t have a live GL context. When a real GL context is available (via the engine pipeline), the handles map to actual GL object names.

PipelineHandle

Opaque handle to a render pipeline (vertex + fragment).

PipelineLayout

Pipeline layout description.

ShaderHandle

Opaque handle to a compiled shader module.

SoftwareContext

Pure-CPU backend that stores everything in RAM. Useful for tests, CI, headless rendering, and platforms without any GPU API.

TextureHandle

Opaque handle to a GPU texture.

Enums

BindingType

Type of a single binding.

GpuBackend

Which GPU API is in use (or Software for CPU fallback).

GpuCommand

A GPU command that can be recorded and submitted.

ShaderStage

Shader stage.

TextureFormat

Texture format.

Traits

BackendContext

Trait that every concrete GPU backend must implement.

Functions

detect_backend

Detect the best available GPU backend on this platform.
