Variants

InvalidInput

Spec, data, or runtime configuration failed input validation (finite/non-negative weights, derivative_guard > 0, supported base_link, frailty constraints, missing block state, etc.).

Fields

reason: String

IncompatibleDimensions

Lengths, row/column counts, basis widths, or coefficient block sizes do not agree (covariance dim vs z, design rows vs n, basis/beta length mismatch, post-update beta length, time constraints A vs b, hessian_matvec dim mismatch, …).

Fields

reason: String

MonotonicityViolation

A row’s transformed time derivative or structural slack fell below derivative_guard (qd1 < guard), violating the monotonicity contract.

Fields

reason: String

NumericalFailure

A numerical step produced a non-finite, non-positive, or internally inconsistent quantity that downstream code cannot consume (e.g. non-positive D, non-positive chi1, calibration derivative disagrees with the direct evaluation, transformed derivative not strictly positive).

Fields

reason: String

IntegrationFailed

An integration / outer-optimization step failed to converge to the requested tolerance (intercept residual, REML outer loop).

Fields

reason: String

UnsupportedConfiguration

The requested combination of options is not implemented (non- probit base link, flexible row calculus with K > 1, spatial psi for unsupported block roles, …).

Fields

reason: String

Trait Implementations

impl Clone for SurvivalMarginalSlopeError

fn clone(&self) -> SurvivalMarginalSlopeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurvivalMarginalSlopeError

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

Formats the value using the given formatter.

impl Display for SurvivalMarginalSlopeError

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

Formats the value using the given formatter.

impl Error for SurvivalMarginalSlopeError

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<String> for SurvivalMarginalSlopeError

fn from(reason: String) -> SurvivalMarginalSlopeError

Inbound conversion from helpers in this module (and adjacent families) that still surface Result<_, String>. The text is preserved verbatim; InvalidInput is the catch-all category for strings produced outside this module.

impl From<SurvivalMarginalSlopeError> for String

fn from(err: SurvivalMarginalSlopeError) -> String

Converts to this type from the input type.
