Struct ResourceBarrier 

pub struct ResourceBarrier {
    pub src_stage: PipelineStage,
    pub dst_stage: PipelineStage,
    pub resource_name: String,
}

Describes a memory/execution barrier between two pipeline stages.

On a real GPU this would translate to a vkCmdPipelineBarrier or wgpu::CommandEncoder::insert_debug_marker. Here it is a pure data type used to validate that the user has not forgotten to insert barriers between dependent passes.

Fields

src_stage: PipelineStage

The stage that writes the resource.

dst_stage: PipelineStage

The stage that reads the resource.

resource_name: String

Human-readable name of the protected resource.

Implementations

impl ResourceBarrier

pub fn new(src: PipelineStage, dst: PipelineStage, name: &str) -> Self

Create a new barrier descriptor.

pub fn is_valid_order(&self) -> bool

Returns true if the barrier is between stages in the correct dependency order (src must come before dst).

Trait Implementations

impl Clone for ResourceBarrier

fn clone(&self) -> ResourceBarrier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceBarrier

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

Formats the value using the given formatter.

impl PartialEq for ResourceBarrier

fn eq(&self, other: &ResourceBarrier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
