Enum LambdaParseError 

pub enum LambdaParseError {
    ParseError(String),
    UnTypedFreeVariable(String),
    ReductionError(ReductionError),
    TypeError(String),

}

Error in parsing a lambda expression

Variants

ParseError(String)

Core error in parsing

UnTypedFreeVariable(String)

A free variable was left untyped

ReductionError(ReductionError)

When the expression was reduced, it lead to an error.

TypeError(String)

There is a type error in apply function types

InnerTypeError(TypeError)

Type error in lower part

ConversionError(LambdaConversionError)

The expression was still a lambda expression and not yet runnable.

Trait Implementations

impl Clone for LambdaParseError

fn clone(&self) -> LambdaParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LambdaParseError

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

Formats the value using the given formatter.

impl Display for LambdaParseError

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

Formats the value using the given formatter.

impl Error for LambdaParseError

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 LambdaParseError

fn from(source: ReductionError) -> Self

Converts to this type from the input type.

impl From<TypeError> for LambdaParseError

fn from(source: TypeError) -> Self

Converts to this type from the input type.

impl<'a, T: Display> From<Vec<Rich<'a, T>>> for LambdaParseError

fn from(value: Vec<Rich<'a, T>>) -> Self

Converts to this type from the input type.
