Struct Dispatch

pub(crate) struct Dispatch {
    module: Box<dyn DynShaderModule>,
    dst_bind_group_layout: Box<dyn DynBindGroupLayout>,
    src_bind_group_layout: Box<dyn DynBindGroupLayout>,
    pipeline_layout: Box<dyn DynPipelineLayout>,
    pipeline: Box<dyn DynComputePipeline>,
    dst_buffer: Box<dyn DynBuffer>,
    dst_bind_group: Box<dyn DynBindGroup>,
}

This machinery requires the following limits:

• max_bind_groups: 2,
• max_dynamic_storage_buffers_per_pipeline_layout: 1,
• max_storage_buffers_per_shader_stage: 2,
• max_storage_buffer_binding_size: 3 * min_storage_buffer_offset_alignment,
• max_push_constant_size: 4,
• max_compute_invocations_per_workgroup 1

These are all indirectly satisfied by DownlevelFlags::INDIRECT_EXECUTION, which is also required for this module’s functionality to work.

Fields

module: Box<dyn DynShaderModule>

dst_bind_group_layout: Box<dyn DynBindGroupLayout>

src_bind_group_layout: Box<dyn DynBindGroupLayout>

pipeline_layout: Box<dyn DynPipelineLayout>

pipeline: Box<dyn DynComputePipeline>

Implementations

impl Dispatch

pub(super) fn new( device: &dyn DynDevice, limits: &Limits, ) -> Result<Self, CreateIndirectValidationPipelineError>

pub(super) fn create_src_bind_group( &self, device: &dyn DynDevice, limits: &Limits, buffer_size: u64, buffer: &dyn DynBuffer, ) -> Result<Option<Box<dyn DynBindGroup>>, DeviceError>

Ok(None) will only be returned if buffer_size is 0.

pub fn params<'a>( &'a self, limits: &Limits, offset: u64, buffer_size: u64, ) -> Params<'a>

pub(super) fn dispose(self, device: &dyn DynDevice)

Trait Implementations

impl Debug for Dispatch

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

Formats the value using the given formatter.
