Struct rafx_framework::graph::RenderGraphImageConstraint

pub struct RenderGraphImageConstraint {
    pub samples: Option<RafxSampleCount>,
    pub format: Option<RafxFormat>,
    pub resource_type: RafxResourceType,
    pub extents: Option<RenderGraphImageExtents>,
    pub layer_count: Option<u32>,
    pub mip_count: Option<u32>,
}

Constraints on an image. Constraints are set per-field and start out None (i.e. unconstrained) The rendergraph will derive specifications from the constraints

Fields

samples: Option<RafxSampleCount>

format: Option<RafxFormat>

resource_type: RafxResourceType

extents: Option<RenderGraphImageExtents>

layer_count: Option<u32>

mip_count: Option<u32>

Implementations

impl RenderGraphImageConstraint

pub fn try_convert_to_specification( self, swapchain_surface_info: &SwapchainSurfaceInfo ) -> Option<RenderGraphImageSpecification>

impl RenderGraphImageConstraint

pub fn can_merge(&self, other: &RenderGraphImageConstraint) -> bool

Returns true if no fields in the two constraints are conflicting

pub fn try_merge(&mut self, other: &RenderGraphImageConstraint) -> bool

Merge other’s constraints into self, but only if there are no conflicts. No modification occurs if any conflict exists

pub fn partial_merge(&mut self, other: &RenderGraphImageConstraint) -> bool

Merge other’s constraints into self. We will merge fields where we can and skip fields with conflicts

pub fn set(&mut self, other: &RenderGraphImageSpecification)

Sets the constraints based on the given specification

Trait Implementations

impl Clone for RenderGraphImageConstraint

fn clone(&self) -> RenderGraphImageConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RenderGraphImageConstraint

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

Formats the value using the given formatter.

impl Default for RenderGraphImageConstraint

fn default() -> RenderGraphImageConstraint

Returns the “default value” for a type.

impl From<RenderGraphImageSpecification> for RenderGraphImageConstraint

fn from(specification: RenderGraphImageSpecification) -> Self

Converts to this type from the input type.
