Enum LanguageTypeError 

pub enum LanguageTypeError {
    PresuppositionError,
    MissingVariable(Variable),
    WrongType {
        input: LanguageResultType,
        output: LanguageResultType,
    },
    TooManySteps(usize),
    TimeOut,
}

Possible errors that can be generated when running a LanguageExpression

Variants

PresuppositionError

A presupposition error in the semantics; occurs when a non-existent entity is referenced.

MissingVariable(Variable)

A variable that is not bound that was used.

WrongType

A type conversion which is violated.

Fields

input: LanguageResultType

The input type of the conversion

output: LanguageResultType

The output type of the conversion

TooManySteps(usize)

The execution ran out of steps

TimeOut

The execution ran out of time (unavailable on wasm).

Trait Implementations

impl Clone for LanguageTypeError

fn clone(&self) -> LanguageTypeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanguageTypeError

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

Formats the value using the given formatter.

impl Display for LanguageTypeError

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

Formats the value using the given formatter.

impl Error for LanguageTypeError

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 LanguageTypeError

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