Validation or backend error from a shared-buffer grouped GEMM.

Validation is completed before the configured backend session is entered, so these errors leave the caller’s output unchanged.

Examples

use tensor4all_tensorbackend::{
    grouped_mat_mul_shared, GroupedGemmError, GroupedGemmJob, GroupedGemmOptions,
};

let error = grouped_mat_mul_shared(
    &[1.0_f64],
    &[1.0_f64],
    &mut [0.0_f64],
    &[GroupedGemmJob::new(1, 0, 0, 1, 1, 1)],
    GroupedGemmOptions::default(),
)
.unwrap_err();
assert!(matches!(error, GroupedGemmError::BufferOutOfBounds { .. }));

Variants

DimensionOverflow

A matrix dimension product overflowed usize.

Fields

job: usize

Zero-based job index.

dimension: &'static str

Dimension product that overflowed.

SpanOverflow

An offset plus the required span overflowed usize.

Fields

job: usize

Zero-based job index.

buffer: &'static str

Buffer whose span overflowed.

BufferOutOfBounds

A job’s input or output span exceeds its caller-owned buffer.

Fields

job: usize

Zero-based job index.

buffer: &'static str

Buffer whose span was rejected.

offset: usize

Starting element offset.

required_end: usize

Exclusive required end offset.

available: usize

Available element count.

OverlappingOutputs

Two output spans overlap without a reduction contract.

Fields

first: usize

First job in source order.

second: usize

Later overlapping job in source order.

IncompatibleSharedLhs

Jobs sharing one left-input offset disagree on its matrix shape.

Fields

first: usize

First job in source order.

second: usize

Later incompatible job in source order.

IncompatibleSharedRhs

Jobs sharing one right-input offset disagree on its matrix shape.

Fields

first: usize

First job in source order.

second: usize

Later incompatible job in source order.

WorkingMemoryExceeded

The descriptor translation exceeds the caller’s working-memory limit.

Fields

required: usize

Bytes required for the translated descriptor array.

limit: usize

Caller-provided maximum.

Backend

The configured provider or tensor view rejected an otherwise validated request.

Fields

source: Error

Original tenferro diagnostic.

Trait Implementations

impl Debug for GroupedGemmError

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

Formats the value using the given formatter.

impl Display for GroupedGemmError

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

Formats the value using the given formatter.

impl Error for GroupedGemmError

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.
