Struct Error 

pub struct Error<'a> { /* private fields */ }

Error type for parse.

Implementations

impl<'a> Error<'a>

pub fn kind(&self) -> Option<ErrorKind>

Get error kind.

Trait Implementations

impl<'a> AddContext<LocatingSlice<&'a str>, ErrorKind> for Error<'a>

fn add_context( self, _input: &LSpan<'a>, _token_start: &<LSpan<'a> as Stream>::Checkpoint, context: ErrorKind, ) -> Self

Append to an existing error custom data

impl<'a> Clone for Error<'a>

fn clone(&self) -> Error<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Error<'a>

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

Formats the value using the given formatter.

impl Display for Error<'_>

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

Formats the value using the given formatter.

impl<'a> Eq for Error<'a>

impl Error for Error<'_>

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<'a, GE> From<Error<'a>> for Error<'a, GE>

fn from(e: ParseError<'a>) -> Self

Converts to this type from the input type.

impl LocatedError for Error<'_>

fn location(&self) -> (usize, usize)

get error happened location in source input.

impl<'a> ParserError<LocatingSlice<&'a str>> for Error<'a>

type Inner = Error<'a>

Generally, Self

fn from_input(input: &LocatingSlice<&'a str>) -> 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<'a> PartialEq for Error<'a>

fn eq(&self, other: &Error<'a>) -> 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.
