Struct rendy_graph::present::PresentBuilder

pub struct PresentBuilder<B: Backend> { /* fields omitted */ }

Presentation node description.

Methods

impl<B> PresentBuilder<B> where
    B: Backend, 

pub fn add_dependency(&mut self, dependency: NodeId) -> &mut Self

Add dependency. Node will be placed after its dependencies.

pub fn with_dependency(self, dependency: NodeId) -> Self

Add dependency. Node will be placed after its dependencies.

pub fn with_image_count(self, image_count: u32) -> Self

Request a number of images in the swapchain. This is not guaranteed to be the final image count, but it will be if supported by the hardware.

Check PresentBuilder::image_count() after calling this function but before building to see the final image count.

pub fn with_blit_filter(self, filter: Filter) -> Self

Set up filter used for resizing when backbuffer size does not match source image size.

Default is Nearest.

pub fn with_present_modes_priority<PF>(self, present_modes_priority: PF) -> Self where
    PF: Fn(PresentMode) -> Option<usize>, 

Request a priority of present modes when creating the swapchain for the PresentNode. Lower index means higher priority.

Check PresentBuilder::present_mode() after calling this function but before building to see the final present mode.

Parameters

• present_modes_priority: A function which takes a gfx_hal::PresentMode and returns an Option<usize>. None indicates not to use this mode, and a higher number returned indicates a higher prioirity for that mode.

Panics

• Panics if none of the provided PresentModes are supported.

pub fn image_count(&self) -> u32

Get image count in presentable swapchain.

pub fn present_mode(&self) -> PresentMode

Get present mode used by node.
