Struct OptionsError 

pub struct OptionsError {
    pub field: &'static str,
    pub reason: &'static str,
}

Error returned when option values fail validation.

Produced by IpmOptions::validate and SolverOptions::validate, and by builder methods (with_*) that validate on assignment.

Fields

field: &'static str

Name of the offending field (e.g. "ipm.eps").

reason: &'static str

Human-readable rejection reason.

Trait Implementations

impl Clone for OptionsError

fn clone(&self) -> OptionsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionsError

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

Formats the value using the given formatter.

impl Display for OptionsError

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

Formats the value using the given formatter.

impl Error for OptionsError

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 PartialEq for OptionsError

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