Enum Error 

#[non_exhaustive]
pub enum Error {
    Unsupported(&'static str),
    InvalidProblem(&'static str),
    MisalignedOperand,
    WorkspaceTooSmall {
        needed: usize,
        got: usize,
    },
    BufferTooSmall {

    CutlassInternal(i32),
    Driver(Error),
}

Errors raised by the safe CUTLASS wrapper.

Re-exported by baracuda-kernels as baracuda_kernels::Error since the kernel facade returns the same error surface for every op family (the cuSOLVER / cuDNN / cuFFT facades all map their library-native status codes into one of these variants).

#[non_exhaustive] — error variants have grown every couple of phases as new failure modes surface (Phase 7 added cuDNN-status fallback paths; Phase 22 added the cuSOLVER facade plumbing). Match arms must include a _ => catch-all so adding a new variant doesn’t break downstream match e { ... } blocks.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unsupported(&'static str)

The requested SKU isn’t available in this build.

Either no arch feature is enabled (no kernels were compiled), or the problem requires a SKU that’s outside the curated v0 set (non-RCR layout, unsupported epilogue, etc.).

InvalidProblem(&'static str)

A problem dimension or stride is invalid (e.g., M, N, or K is non-positive).

MisalignedOperand

A pointer or stride is misaligned for the selected kernel’s tensor-op instructions.

WorkspaceTooSmall

The provided workspace is too small for the selected plan or Workspace::None was passed when scratch was required.

Fields

needed: usize

Required workspace size in bytes.

got: usize

Provided workspace size in bytes.

BufferTooSmall

A device buffer is too small for the declared matrix shape and stride.

Fields

needed: usize

Minimum elements required for (rows, cols, ld).

got: usize

Elements available in the supplied slice.

CutlassInternal(i32)

CUTLASS reported an internal error during launch (typically a kernel-launch failure surfaced through cudaGetLastError).

Driver(Error)

Underlying baracuda-driver error (context, stream, etc.).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error<CUresult>> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
