Enum RemoveConstraintError 

pub enum RemoveConstraintError {
    UnknownConstraint,
    InternalSolverError(InternalSolverError),
}

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

Variants

UnknownConstraint

The constraint specified was not already in the solver, so cannot be removed.

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 RemoveConstraintError

fn clone(&self) -> RemoveConstraintError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemoveConstraintError

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

Formats the value using the given formatter.

impl Display for RemoveConstraintError

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

Formats the value using the given formatter.

impl Error for RemoveConstraintError

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 RemoveConstraintError

fn from(source: InternalSolverError) -> Self

Converts to this type from the input type.
