}

Configuration, metadata or explicit parameter-group error for Muon. Device execution faults remain backend errors; no host fallback is attempted.

Variants

InvalidConfig(&'static str)

Invalid hyperparameter or unsupported numerical mode.

ExpectedMatrix

Muon operates on a complete matrix, not an arbitrary-rank tensor.

Fields

rank: usize

Actual tensor rank.

EmptyMatrix

A matrix dimension is zero.

ShapeMismatch(&'static str)

Gradient or restored momentum has incompatible geometry.

DTypeMismatch(&'static str)

Gradient or restored momentum has a different element format.

DeviceMismatch(&'static str)

Gradient or restored momentum is on a different device.

EmptyMuonGroup

The Muon group was left empty.

DuplicateParameter(u64)

A selected id was supplied twice.

UnknownParameter(u64)

A selected id is absent from the module.

FrozenParameter(u64)

A selected Muon parameter is frozen.

ModelChanged

A module’s ids/shapes changed, or tied aliases disagree.

UnusedGradients

A gradient refers to an unknown or frozen parameter.

IncompatibleRecord

A record belongs to another grouping, geometry, configuration or schema.

UnsupportedDistributed

This API is deliberately limited to full, synchronized local matrices.

Trait Implementations

impl Clone for MuonError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MuonError

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

Formats the value using the given formatter.

impl Display for MuonError

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

Formats the value using the given formatter.

impl Eq for MuonError

impl Error for MuonError

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 MuonError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
