Enum StatsError 

#[non_exhaustive]
pub enum StatsError {
    Shape {
        message: &'static str,
    },
    RankDeficient {
        rank: usize,
        ncols: usize,
    },

    Backend(String),
}

Statistical / linear algebra errors.

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.

Shape

Shape mismatch.

Fields

message: &'static str

Context.

RankDeficient

Rank deficiency / singular design.

Fields

rank: usize

Detected rank.

ncols: usize

Number of columns.

NonPositiveVariance

Materially non-positive variance after inclusion–exclusion (not FP noise).

Fields

message: &'static str

Context.

Unsupported

Requested option is not implemented on this code path.

Fields

message: &'static str

Context.

Backend(String)

Backend failure.

Trait Implementations

impl Clone for StatsError

fn clone(&self) -> StatsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatsError

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

Formats the value using the given formatter.

impl Display for StatsError

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

Formats the value using the given formatter.

impl Eq for StatsError

impl Error for StatsError

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 StatsError

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

Equality operator ==.

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

Inequality operator !=.
