        reason: String,

    },
    ConstraintViolation {

}

Typed errors emitted by the survival location-scale family pipeline.

Each variant carries a pre-formatted reason string so Display is byte-equivalent to the original format!(...) outputs the module used before the typed-error migration. The category split lets callers pattern-match on the failure kind without dragging the string apart.

Variants

DimensionMismatch

Row/column/length disagreement between vectors, matrices, designs, penalty blocks, or coefficient/parameter dimensions.

Fields

reason: String

InvalidConfiguration

Spec-level validation: tolerances, iteration caps, knot-vector lengths, time intervals, weight values, or missing/contradictory configuration fields the user supplied.

Fields

reason: String

ConstraintViolation

Structural constraint violated at runtime: monotonicity guards, lower bounds on coefficients, nonnegativity, derivative-basis sign, or values outside an allowed semantic range.

Fields

reason: String

NumericalFailure

A numerical step produced a non-finite or out-of-domain value downstream code cannot consume (NaN products, invalid pdf, survival probability out of (0,1], etc.).

Fields

reason: String

InternalInvariant

Internal invariant about pipeline state (empty block markers, unexpected ranks, schema/state inconsistencies surfaced from inner helpers).

Fields

reason: String

Trait Implementations

impl Clone for SurvivalLocationScaleError

fn clone(&self) -> SurvivalLocationScaleError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurvivalLocationScaleError

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

Formats the value using the given formatter.

impl Display for SurvivalLocationScaleError

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

Formats the value using the given formatter.

impl Error for SurvivalLocationScaleError

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 SurvivalLocationScaleError

fn from(err: BlockCountMismatch) -> SurvivalLocationScaleError

Converts to this type from the input type.

impl From<String> for SurvivalLocationScaleError

fn from(reason: String) -> SurvivalLocationScaleError

Inbound conversion from the many Result<_, String> helpers this module still calls into. The text is preserved verbatim; we only pick a generic category so external messages flow through ? without per-callsite .map_err.

impl From<SurvivalLocationScaleError> for String

fn from(err: SurvivalLocationScaleError) -> String

Converts to this type from the input type.
