    },

    },
    InvalidDimension {

        value: u32,
    },
}

Error type for launch parameter validation.

These variants describe specific constraint violations that would cause a kernel launch to fail at the driver level.

Variants

BlockSizeExceedsLimit

The total number of threads per block exceeds the device maximum.

Fields

requested: u32

Requested total threads per block.

max: u32

Maximum allowed by the device.

GridSizeExceedsLimit

A grid dimension exceeds the device maximum.

Fields

requested: u32

Requested grid size in the offending dimension.

max: u32

Maximum allowed by the device.

SharedMemoryExceedsLimit

The requested dynamic shared memory exceeds the device maximum.

Fields

requested: u32

Requested shared memory in bytes.

max: u32

Maximum allowed by the device.

InvalidDimension

A dimension value is invalid (e.g., zero).

Fields

dim: &'static str

Name of the dimension (e.g., “block.x”, “grid.z”).

value: u32

The invalid value.

Trait Implementations

impl Clone for LaunchError

fn clone(&self) -> LaunchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LaunchError

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

Formats the value using the given formatter.

impl Display for LaunchError

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

Formats the value using the given formatter.

impl Error for LaunchError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for LaunchError

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