Describes information about what a Surface’s presentation capabilities are. Fetch this with Adapter::surface_capabilities.

Fields

formats: Vec<TextureFormat>

List of supported texture formats.

Must be at least one.

maximum_frame_latency: RangeInclusive<u32>

Range for the number of queued frames.

This adjusts either the swapchain frame count to value + 1 - or sets SetMaximumFrameLatency to the value given, or uses a wait-for-present in the acquire method to limit rendering such that it acts like it’s a value + 1 swapchain frame set.

• maximum_frame_latency.start must be at least 1.
• maximum_frame_latency.end must be larger or equal to maximum_frame_latency.start.

current_extent: Option<Extent3d>

Current extent of the surface, if known.

usage: TextureUses

Supported texture usage flags.

Must have at least TextureUses::COLOR_TARGET

present_modes: Vec<PresentMode>

List of supported V-sync modes.

Must be at least one.

composite_alpha_modes: Vec<CompositeAlphaMode>

List of supported alpha composition modes.

Must be at least one.
