Enum GamlssError 

pub enum GamlssError {
    DimensionMismatch {
        reason: String,
    },
    InvalidInput {
        reason: String,
    },
    NonFinite {
        reason: String,
    },
    UnsupportedConfiguration {
        reason: String,
    },
    ConstraintViolation {
        reason: String,
    },
    NumericalFailure {
        reason: String,
    },
}

Typed errors surfaced from this module’s helpers and family implementations. The Display impl writes the carried reason verbatim, so callers that historically returned Result<_, String> keep their user-visible text byte-for-byte identical after coercion via the From<GamlssError> for String impl below.

Variants

DimensionMismatch

Shape, length, row, or column mismatches between matrices, vectors, specs, or block configurations.

Fields

reason: String

InvalidInput

Generic input validation that doesn’t fit a more specific variant (e.g. positivity-of-response checks, shape parameter must be finite > 0).

Fields

reason: String

NonFinite

Non-finite values discovered in inputs, coefficients, seeds, or intermediate quantities required to remain finite.

Fields

reason: String

UnsupportedConfiguration

A model configuration or feature combination is not supported by the requested family / link / engine (e.g. identity link on a binomial mean-wiggle family, unexpected design-map variant).

Fields

reason: String

ConstraintViolation

Bound, range, monotonicity, or sign constraints violated by supplied parameters or coefficients.

Fields

reason: String

NumericalFailure

Numerical failures during inner solves, integration, or optimization (invalid probabilities, non-finite log-likelihood, invalid λ, divergence).

Fields

reason: String

Trait Implementations

impl Debug for GamlssError

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

Formats the value using the given formatter.

impl Display for GamlssError

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

Formats the value using the given formatter.

impl Error for GamlssError

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 From<BlockCountMismatch> for GamlssError

fn from(err: BlockCountMismatch) -> GamlssError

Converts to this type from the input type.

impl From<GamlssError> for String

fn from(err: GamlssError) -> String

Converts to this type from the input type.
