Errors that can occur during quantization kernel operations.

Variants

UnsupportedType

The requested quantization type is not yet implemented.

Fields

quant_type: String

Display name of the unsupported type.

BlockSizeMismatch

Block size does not match expected value for the quantization type.

Fields

expected: usize

Expected block size.

got: usize

Actual block size.

DimensionMismatch

Matrix/vector dimension mismatch in a kernel operation.

Fields

expected: usize

Expected dimension.

got: usize

Actual dimension.

KernelError

A low-level kernel computation error.

Fields

message: String

Description of the kernel error.

BlockCountMismatch

Block count does not match the expected value for the tensor dimensions.

Fields

expected: usize

Expected number of blocks.

got: usize

Actual number of blocks.

BufferTooSmall

Data buffer is too small for the operation.

Fields

needed: usize

Required buffer size in bytes.

available: usize

Available buffer size in bytes.

Internal

Internal error (e.g., lock poisoning).

Fields

message: String

Description of the internal error.

FloatGemmFailed(String)

Float GEMM (F16/BF16/F32) computation failure.

Trait Implementations

impl Debug for QuantError

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

Formats the value using the given formatter.

impl Display for QuantError

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

Formats the value using the given formatter.

impl Error for QuantError

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.
