Enum ConjoiningError 

pub enum ConjoiningError {
    MismatchingTypes(LambdaType, LambdaType),
    DoesntReturnT(LambdaType),
    ReductionError(ReductionError),
}

An error which results from a failed application of RootedLambdaPool::conjoin

Variants

MismatchingTypes(LambdaType, LambdaType)

Both arguments have to have the same type

DoesntReturnT(LambdaType)

The type must return a truth value

ReductionError(ReductionError)

One of the arguments has an internal problem leading to reduction errors

Trait Implementations

impl Clone for ConjoiningError

fn clone(&self) -> ConjoiningError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConjoiningError

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

Formats the value using the given formatter.

impl Display for ConjoiningError

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

Formats the value using the given formatter.

impl Error for ConjoiningError

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<ReductionError> for ConjoiningError

fn from(source: ReductionError) -> Self

Converts to this type from the input type.

impl PartialEq for ConjoiningError

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