Variants

DimensionMismatch

Tensor dimension does not match the expected value.

Fields

expected: usize

got: usize

EmptyInput(&'static str)

The input slice is empty when at least one element is required.

InvalidScale

A quantization scale is zero or negative (would produce NaN/Inf).

Fields

scale: f32

InvalidBitWidth

A quantization bit-width is outside the valid range [1, 16].

Fields

bits: u32

GroupSizeMismatch

The requested group size does not evenly divide the tensor length.

Fields

len: usize

group: usize

CalibrationRequired(&'static str)

A calibration dataset is required but was not provided.

SingularHessian

The Hessian matrix is singular or near-singular.

Fields

min_diag: f32

TeacherStudentMismatch

Distillation teacher and student outputs have incompatible shapes.

Fields

teacher: usize

student: usize

AllZeroPruning

A pruning threshold produced a 100% sparse tensor (no weights remain).

Fields

threshold: f32

n: usize

NonFiniteFp8(f32)

FP8 format encoding received a NaN/Inf value.

InfeasibleCompressionTarget

Mixed-precision policy could not satisfy the requested compression ratio.

Fields

target: f32

InvalidConfig(String)

Generic configuration error.

Trait Implementations

impl Clone for QuantError

fn clone(&self) -> QuantError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.

impl PartialEq for QuantError

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