Struct ThreadGroupContext 

pub struct ThreadGroupContext {
    pub group_id: usize,
    pub local_id: usize,
    pub group_size: usize,
    pub global_id: usize,
}

Execution context passed to each invocation of a kernel closure.

Mirrors the built-in variables available in GLSL/HLSL/WGSL compute shaders.

Fields

group_id: usize

Index of the work group this thread belongs to (gl_WorkGroupID).

local_id: usize

Thread index within the work group (gl_LocalInvocationID).

group_size: usize

Number of threads per work group.

global_id: usize

Flat global index across all work groups (gl_GlobalInvocationID).

Equals group_id * group_size + local_id.

Implementations

impl ThreadGroupContext

pub fn new(group_id: usize, local_id: usize, group_size: usize) -> Self

Construct a context from its constituent indices.

Trait Implementations

impl Clone for ThreadGroupContext

fn clone(&self) -> ThreadGroupContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadGroupContext

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

Formats the value using the given formatter.

impl PartialEq for ThreadGroupContext

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

impl Copy for ThreadGroupContext

impl Eq for ThreadGroupContext

impl StructuralPartialEq for ThreadGroupContext
