Enum PCAError 

pub enum PCAError {
    EmptyMatrix,
    InvalidInput(String),
    DecompositionFailed,
}

Error type for PCA operations.

Variants

EmptyMatrix

Input matrix is empty.

InvalidInput(String)

Invalid user input.

DecompositionFailed

Decomposition failed.

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 IntoNabledError for PCAError

fn into_nabled_error(self) -> NabledError

Convert domain-specific error into shared taxonomy.

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.
