Trait ComputePass 

pub trait ComputePass<'pass> {
    // Required methods
    fn set_pipeline(&mut self, pipeline: &'pass ComputePipelineId);
    fn set_bind_group(&mut self, index: u32, bind_group: &'pass BindGroupId);
    fn dispatch_workgroups(&mut self, x: u32, y: u32, z: u32);
}

A trait representing an active compute pass, used for recording dispatch commands.

A ComputePass object is obtained from a CommandEncoder and provides methods to set the compute pipeline, bind resources, and dispatch workgroups.

The 'pass lifetime ensures that the pass object cannot outlive the CommandEncoder that created it, and that any resources bound to it also live long enough.

Required Methods

fn set_pipeline(&mut self, pipeline: &'pass ComputePipelineId)

Sets the active compute pipeline for subsequent dispatch calls.

Arguments

• pipeline - The compute pipeline to use

fn set_bind_group(&mut self, index: u32, bind_group: &'pass BindGroupId)

Binds a bind group to a specific binding slot.

Arguments

• index - The bind group index (must match shader @group(N) declarations)
• bind_group - The bind group to bind

fn dispatch_workgroups(&mut self, x: u32, y: u32, z: u32)

Dispatches compute workgroups.

The total number of invocations is (x * y * z) * workgroup_size where workgroup_size is defined in the compute shader with @workgroup_size.

Arguments

• x - Number of workgroups in the X dimension
• y - Number of workgroups in the Y dimension
• z - Number of workgroups in the Z dimension
