Enum SuggestValueError 

pub enum SuggestValueError {
    UnknownEditVariable,
    InternalSolverError(InternalSolverError),
}

The possible error conditions that Solver::suggest_value can fail with.

Variants

UnknownEditVariable

The specified variable was not an edit variable in the solver, so cannot have its value suggested.

InternalSolverError(InternalSolverError)

The solver entered an invalid state. If this occurs please report the issue. This variant specifies additional details as a string.

Trait Implementations

impl Clone for SuggestValueError

fn clone(&self) -> SuggestValueError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SuggestValueError

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

Formats the value using the given formatter.

impl Display for SuggestValueError

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

Formats the value using the given formatter.

impl Error for SuggestValueError

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<InternalSolverError> for SuggestValueError

fn from(source: InternalSolverError) -> Self
