Struct EmptyError

pub struct EmptyError;

Track an error occurred without any other StrContext

Trait Implementations

impl<I: Stream, C> AddContext<I, C> for EmptyError

fn add_context( self, _input: &I, _token_start: &<I as Stream>::Checkpoint, _context: C, ) -> Self

Append to an existing error custom data

impl Clone for EmptyError

fn clone(&self) -> EmptyError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EmptyError

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

Formats the value using the given formatter.

impl Display for EmptyError

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

Formats the value using the given formatter.

impl ErrorConvert<EmptyError> for EmptyError

fn convert(self) -> EmptyError

Transform to another error type

impl<I, E> FromExternalError<I, E> for EmptyError

fn from_external_error(_input: &I, _e: E) -> Self

Like ParserError::from_input but also include an external error.

impl<I: Stream> ParserError<I> for EmptyError

type Inner = EmptyError

Generally, Self

fn from_input(_: &I) -> Self

Creates an error from the input position

fn into_inner(self) -> Result<Self::Inner, Self>

Unwrap the mode, returning the underlying error, if present

fn assert(input: &I, _message: &'static str) -> Self

where I: Debug,

Process a parser assertion

fn incomplete(input: &I, _needed: Needed) -> Self

There was not enough data to determine the appropriate action

fn append(self, _input: &I, _token_start: &<I as Stream>::Checkpoint) -> Self

Like ParserError::from_input but merges it with the existing error.

fn or(self, other: Self) -> Self

Combines errors from two different parse branches.

fn is_backtrack(&self) -> bool

Is backtracking and trying new parse branches allowed?

fn is_incomplete(&self) -> bool

Is more data Needed

fn needed(&self) -> Option<Needed>

Extract the Needed data, if present

impl PartialEq for EmptyError

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