Struct GraphchainInfo 

pub struct GraphchainInfo {
    pub acquire_timeout: u64,
    pub composite_alpha: CompositeAlphaFlagsKHR,
    pub clipped: bool,
    pub frame_capacity: usize,
    pub height: u32,
    pub min_image_count: u32,
    pub present_mode: PresentModeKHR,
    pub surface: SurfaceFormatKHR,
    pub width: u32,
}

Information used to create a Graphchain instance.

Fields

acquire_timeout: u64

Timeout in nanoseconds used when acquiring the next image.

Do not use u64::MAX on surfaces where acquire forward progress cannot be guaranteed.

composite_alpha: CompositeAlphaFlagsKHR

Alpha compositing mode used by the presentation engine.

clipped: bool

Whether to clip pixels obscured by other windows on the native surface.

frame_capacity: usize

The requested frame capacity used for in-flight graphchain work.

The effective live capacity may be raised at runtime to match the swapchain image count. That resolved value is reflected through EffectiveGraphchainInfo.

height: u32

The initial height of the surface.

min_image_count: u32

The minimum number of presentable images that the application needs.

present_mode: PresentModeKHR

vk::PresentModeKHR determines timing and queueing with which frames are displayed.

surface: SurfaceFormatKHR

The format and color space of the surface.

width: u32

The initial width of the surface.

Implementations
