Enum MultivariateStudentError

#[non_exhaustive]
pub enum MultivariateStudentError {
    ScaleInvalid,
    LocationInvalid,
    FreedomInvalid,
    DimensionMismatch,
    CholeskyFailed,
}

Represents the errors that can occur when creating a MultivariateStudent.

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.

ScaleInvalid

The scale matrix is asymmetric or contains a NaN.

LocationInvalid

The location vector contains a NaN.

FreedomInvalid

The degrees of freedom are NaN, zero or less than zero.

DimensionMismatch

The amount of rows in the location vector is not equal to the amount of rows in the scale matrix.

CholeskyFailed

After all other validation, computing the Cholesky decomposition failed. This means that the scale matrix is not definite-positive.

Trait Implementations

impl Clone for MultivariateStudentError

fn clone(&self) -> MultivariateStudentError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultivariateStudentError

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

Formats the value using the given formatter.

impl Display for MultivariateStudentError

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

Formats the value using the given formatter.

impl Error for MultivariateStudentError

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 Hash for MultivariateStudentError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MultivariateStudentError

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