Module renderer

Rendering functionality and abstractions

Collection of common traits and implementations to facilitate (possible hardware-accelerated) rendering.

Supported rendering apis:

Modules§

damage: Helper for effective output damage tracking
element: Common base for elements that can be drawn by a Renderer
glesrenderer_gl: Implementation of the rendering traits using OpenGL ES 2
glowrenderer_glow: Integration for using glow on top of smithays OpenGL ES 2 renderer
multigpurenderer_multi: This module aims to make multi-gpu setups easier to handle for compositors.
pixmanrenderer_pixman: Implementation of the rendering traits using pixman
sync: Helper for synchronizing rendering operations
testrenderer_test
utils: Utility module for helpers around drawing WlSurfaces and RenderElements with Renderers.

Color32F: A four-component color representing pre-multiplied RGBA color values
ContextId: Identifies a renderer context for a specific texture type.
DebugFlags: Debug flags that can be enabled at runtime
ErasedContextId: A type-erased ContextId without the Texture generic.

BufferTypewayland_frontend: Buffer type of a given wl_buffer, if managed by smithay
TextureFilter: Texture filtering methods

Bind: Abstraction for Renderers, that can render into different targets
Blit: Trait for renderers supporting blitting contents from one framebuffer to another.
BlitFrame: Trait for frames supporting blitting contents from/to the current framebuffer to/from another.
ExportMem: Trait for renderers supporting exporting contents of framebuffers or textures into memory.
Frame: Helper trait for Renderer, which defines a rendering api for a currently in-progress frame during Renderer::render.
ImportAllwayland_frontend: Common trait for renderers of any wayland buffer type
ImportDma: Trait for Renderers supporting importing dmabufs.
ImportDmaWlwayland_frontend: Trait for Renderers supporting importing dmabuf-based wl_buffers
ImportEglwayland_frontend and backend_egl and use_system_lib: Trait for Renderers supporting importing wl_drm-based buffers.
ImportMem: Trait for Renderers supporting importing bitmaps from memory.
ImportMemWlwayland_frontend: Trait for Renderers supporting importing wl_buffers using shared memory.
Offscreen: Trait for renderers that support creating offscreen framebuffers to render into.
Renderer: Abstraction of commonly used rendering operations for compositors.
RendererSuper: Workaround for https://github.com/rust-lang/rust/issues/87479, please look at Renderer instead.
Texture: A two dimensional texture
TextureMapping: A downloaded texture buffer

buffer_dimensionswayland_frontend: Returns the dimensions of a wl_buffer
buffer_has_alphawayland_frontend: Returns if the buffer has an alpha channel
buffer_typewayland_frontend: Returns the type of a wl_buffer
buffer_y_inverted: Returns if the underlying buffer is y-inverted
