Struct SurfaceCapabilities 

pub struct SurfaceCapabilities {
    pub formats: Vec<SurfaceFormatCapabilities>,
    pub maximum_frame_latency: RangeInclusive<u32>,
    pub current_extent: Option<Extent3d>,
    pub usage: TextureUses,
    pub present_modes: Vec<PresentMode>,
    pub composite_alpha_modes: Vec<CompositeAlphaMode>,
}

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

Fields

formats: Vec<SurfaceFormatCapabilities>

List of supported texture formats together with the color spaces supported for each format.

Must be at least one. At most one entry per format, each with a non-empty set of color spaces.

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 wgt::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.

Implementations

impl SurfaceCapabilities

pub fn texture_formats(&self) -> impl Iterator<Item = TextureFormat> + '_

Returns the supported texture formats, dropping the per-format color-space information carried in Self::formats.

Trait Implementations

impl Clone for SurfaceCapabilities

fn clone(&self) -> SurfaceCapabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SurfaceCapabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
