Struct LaunchPlan 

pub struct LaunchPlan {
    pub element_count: u32,
    pub workgroup: [u32; 3],
    pub grid: [u32; 3],
    pub param_words: Vec<u32>,
    pub max_binding_alignment: usize,
}

Fully prepared launch metadata shared by concrete drivers.

Fields

element_count: u32

Logical element count passed to the lowered kernel.

workgroup: [u32; 3]

Effective workgroup/block shape after dispatch overrides.

grid: [u32; 3]

Effective grid shape after dispatch overrides or inference.

param_words: Vec<u32>

Per-buffer element-count metadata uploaded as the shared params buffer.

max_binding_alignment: usize

Maximum preferred alignment across all launch bindings.

Concrete drivers use this to pick upload staging and device-buffer allocation paths without re-inspecting Program buffer declarations.

Implementations

impl LaunchPlan

pub fn new() -> Self

Empty launch plan with reusable parameter-word storage.

pub fn from_bindings( program: &Program, bindings: &[Binding], config: &DispatchConfig, limits: LaunchGeometryLimits, ) -> Result<Self, BackendError>

Prepare dispatch geometry and parameter words from a validated binding plan.

Errors

Returns when caller overrides produce zero dimensions, overflow the logical launch element count, or exceed backend-reported launch limits.

pub fn prepare_into( &mut self, program: &Program, bindings: &[Binding], config: &DispatchConfig, limits: LaunchGeometryLimits, ) -> Result<(), BackendError>

Prepare dispatch geometry and parameter words, reusing this plan’s buffers.

Errors

Returns when caller overrides produce zero dimensions, overflow the logical launch element count, or exceed backend-reported launch limits.

Trait Implementations

impl Clone for LaunchPlan

fn clone(&self) -> LaunchPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LaunchPlan

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

Formats the value using the given formatter.

impl Default for LaunchPlan

fn default() -> Self

Returns the “default value” for a type.

impl Eq for LaunchPlan

impl PartialEq for LaunchPlan

fn eq(&self, other: &LaunchPlan) -> 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.
