Struct LeftoverError

pub struct LeftoverError<O> { /* private fields */ }

The parser returned success, but there was unexpected leftover input.

This error contains the parsed item, which can be accessed using LeftoverError::recover.

Implementations

impl<O> LeftoverError<O>

pub fn recover(self) -> O

Consumes this error and returns the parsed output.

pub fn map_parsed<O2>(self, map: impl FnOnce(O) -> O2) -> LeftoverError<O2>

Map the parsed output into some other type.

Trait Implementations

impl<O: Clone> Clone for LeftoverError<O>

fn clone(&self) -> LeftoverError<O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<O: Debug> Debug for LeftoverError<O>

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

Formats the value using the given formatter.

impl<O> Display for LeftoverError<O>

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

Formats the value using the given formatter.

impl<O> Error for LeftoverError<O>

where Self: Debug,

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<T> From<LeftoverError<T>> for ParseProgramError<T>

fn from(err: LeftoverError<T>) -> Self

Converts to this type from the input type.

impl<T> From<LeftoverError<T>> for SyntaxError<T>

fn from(err: LeftoverError<T>) -> Self

Converts to this type from the input type.

impl<O: PartialEq> PartialEq for LeftoverError<O>

fn eq(&self, other: &LeftoverError<O>) -> 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.
