This crate provides utilities for the Fuchsia display-coordinator API.

Structs§

BufferCollectionId: Strongly typed wrapper around a sysmem buffer collection ID.
BufferId: Strongly typed wrapper around a sysmem buffer identifier, including a collection ID and the index of the buffer. Corresponds to [fuchsia.hardware.display/BufferId].
ClientCompositionAction: Represents a suggested client composition action generated by the driver.
Color: Enhances the fuchsia.hardware.display.typers.Color FIDL struct.
Coordinator: Client abstraction for the fuchsia.hardware.display.Coordinator protocol. Instances can be safely cloned and passed across threads.
DisplayConfig: Represents an individual display configuration.
DisplayId: Strongly typed wrapper around a display ID.
DisplayInfo: Enhances the fuchsia.hardware.display.Info FIDL struct.
Event: A zircon event that has been registered with the display driver.
EventId: Strongly typed wrapper around a display driver event ID.
Image: Represents an allocated image buffer that can be assigned to a display layer.
ImageId: Strongly typed wrapper around an image ID.
ImageParameters: Input parameters for constructing an image.
Layer: Represents an individual layer configuration.
LayerId: Strongly typed wrapper around a display layer ID.
VsyncEvent: A vsync event payload.

ConfigError: An error generated by fuchsia.hardware.display.Controller.CheckConfig.
Error: Library error type.
LayerConfig: LayerConfig is a variant type of the two distinct layer configuration types that are supported by the display driver: Primary and Color.
PixelFormat: Pixel format definitions that bridge different versions of sysmem / images2 formats Fuchsia uses for display and GPU drivers’ internal image type representation.

get_bytes_per_pixel: Get number of bytes per pixel for given pixel_format. Currently only packed pixel formats are supported. Planar formats (e.g. NV12) are not supported.
