Module smithay::backend::renderer

Rendering functionality and abstractions

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

Supported rendering apis:

• Raw OpenGL ES 2

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.

Structs

• DebugFlags
  Debug flags that can be enabled at runtime

Enums

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

Traits

• Bind
  Abstraction for Renderers, that can render into different targets
• Blit
  Trait for renderers supporting blitting contents from one framebuffer to 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.
• Texture
  A two dimensional texture
• TextureMapping
  A downloaded texture buffer
• Unbind
  Functionality to unbind the current rendering target

Functions

• 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_invertedwayland_frontend
  Returns if the underlying buffer is y-inverted
