Struct Limits 

pub struct Limits {
    pub max_workgroup_size_x: u32,
    pub max_workgroup_size_y: u32,
    pub max_workgroup_size_z: u32,
    pub max_invocations_per_workgroup: u32,
    pub max_workgroups_per_dim: u32,
}

A conservative, portable subset of the WebGPU compute limits a planner needs. Field names follow the WebGPU / wgpu limit names.

Limits::portable_default reflects the guaranteed lower bounds every conformant WebGPU adapter must expose, so planning against it yields dispatches that run everywhere.

Fields

max_workgroup_size_x: u32

maxComputeWorkgroupSizeX.

max_workgroup_size_y: u32

maxComputeWorkgroupSizeY.

max_workgroup_size_z: u32

maxComputeWorkgroupSizeZ.

max_invocations_per_workgroup: u32

maxComputeInvocationsPerWorkgroup — product of the three axes must not exceed this.

max_workgroups_per_dim: u32

maxComputeWorkgroupsPerDimension.

Implementations

impl Limits

pub fn portable_default() -> Self

The WebGPU guaranteed lower bounds (Chrome / Firefox / Safari all expose at least these).

256 invocations, (256, 256, 64) per-axis sizes, 65535 workgroups per dimension.

pub fn desktop_default() -> Self

A higher-end desktop profile (e.g. discrete NVIDIA / AMD via Vulkan) exposing 1024 invocations per workgroup.

Trait Implementations

impl Clone for Limits

fn clone(&self) -> Limits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Limits

impl Debug for Limits

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

Formats the value using the given formatter.

impl Eq for Limits

impl PartialEq for Limits

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