Enum NaturalGradientTuningError 

#[non_exhaustive]
pub enum NaturalGradientTuningError {
    EmptyMeasurements,
    FisherMatrixShape {
        measurements: usize,
        cells: usize,
    },
    ZeroTemperature,
}

Errors returned by natural-gradient autotune policy construction.

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.

EmptyMeasurements

No latency samples were provided.

FisherMatrixShape

The inverse-Fisher square-root matrix was not n * n.

Fields

measurements: usize

Number of latency samples.

cells: usize

Number of fixed-point cells in the supplied matrix.

ZeroTemperature

The softmax temperature was zero.

Trait Implementations

impl Clone for NaturalGradientTuningError

fn clone(&self) -> NaturalGradientTuningError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NaturalGradientTuningError

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

Formats the value using the given formatter.

impl Display for NaturalGradientTuningError

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

Formats the value using the given formatter.

impl Eq for NaturalGradientTuningError

impl Error for NaturalGradientTuningError

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 NaturalGradientTuningError

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