`shrinkage::FitError`

Shrinkage for Rust · rust · 0.3.0

Source: src/error.rs

pub enum FitError<E = std::convert::Infallible>

Input, numerical, or backend failure. Backend errors retain their type.

The default source type is Infallible, used by prediction and in-memory matrix backends. Optimization iteration limits are reported in the fitted result.

Variants

`Backend`

Source: src/error.rs

Backend { operation: &'static str, source: E }

A matrix backend failed while computing statistics or a design product.

`operation`

Source: src/error.rs

operation: &'static str

Operation that requested the backend capability.

`source`

Source: src/error.rs

source: E

Original backend error.

`InvalidInput`

Source: src/error.rs

InvalidInput { message: String }

Invalid data, dimensions, options, or backend-provided statistics.

`message`

Source: src/error.rs

message: String

Description of the invalid input, including its location when available.

`LineSearchFailure`

Source: src/error.rs

LineSearchFailure { iteration: usize, step: f64 }

Backtracking could not establish the solver's acceptance condition.

`iteration`

Source: src/error.rs

iteration: usize

Iteration whose trial steps were rejected.

`step`

Source: src/error.rs

step: f64

Last attempted step size.

`NumericalFailure`

Source: src/error.rs

NumericalFailure { operation: &'static str, iteration: usize }

Arithmetic produced a nonfinite value from finite inputs.

`iteration`

Source: src/error.rs

iteration: usize

Iteration during which the failure occurred; zero denotes initialization.

`operation`

Source: src/error.rs

operation: &'static str

Operation that encountered the nonfinite value.

`UnsupportedCombination`

Source: src/error.rs

UnsupportedCombination { solver: &'static str, reason: String, suggestion: &'static str }

The selected solver cannot support a component or stopping rule.

`reason`

Source: src/error.rs

reason: String

Missing capability or incompatible selection.

`solver`

Source: src/error.rs

solver: &'static str

Solver whose requirements were not met.

`suggestion`

Source: src/error.rs

suggestion: &'static str

A supported alternative or the capability needed to proceed.
