Enum PcaError 

pub enum PcaError {
    InsufficientData {
        samples: usize,
        features: usize,
    },
    InvalidComponents {
        requested: usize,
        max: usize,
    },
    DimensionMismatch,
}

Errors arising from PCA operations.

Variants

InsufficientData

Not enough samples or features to perform PCA.

Fields

samples: usize

features: usize

InvalidComponents

Requested more components than the dimensionality allows.

Fields

requested: usize

max: usize

DimensionMismatch

Input dimensionality does not match the fitted model.

Trait Implementations

impl Clone for PcaError

fn clone(&self) -> PcaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PcaError

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

Formats the value using the given formatter.

impl Display for PcaError

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

Formats the value using the given formatter.

impl Error for PcaError

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 PcaError

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