Struct winnow::error::Error

pub struct Error<I> {
    pub input: I,
    pub kind: ErrorKind,
}

Default error type, only contains the error’ location and kind

This is a low-overhead error that only provides basic information. For less overhead, see (). Fore more information, see VerboseError. :w Note: context and inner errors (like from Parser::map_res) will be dropped.

Fields

input: I

The input stream, pointing to the location where the error occurred

kind: ErrorKind

A rudimentary error kind

Implementations

impl<I> Error<I>

pub fn new(input: I, kind: ErrorKind) -> Error<I>

Creates a new basic error

impl<'i, I: ToOwned + ?Sized> Error<&'i I>

pub fn into_owned(self) -> Error<<I as ToOwned>::Owned>

Obtaining ownership

Trait Implementations

impl<I: Clone> Clone for Error<I>

fn clone(&self) -> Error<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I, C> ContextError<I, C> for Error<I>

fn add_context(self, _input: I, _ctx: C) -> Self

Append to an existing error custom data

impl<I: Debug> Debug for Error<I>

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

Formats the value using the given formatter.

impl<I: Display> Display for Error<I>

The Display implementation allows the std::error::Error implementation

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

Formats the value using the given formatter.

impl<I: Debug + Display + Sync + Send + 'static> Error for Error<I>

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl<I> ErrorConvert<Error<(I, usize)>> for Error<I>

fn convert(self) -> Error<(I, usize)>

Transform to another error type

impl<I> ErrorConvert<Error<I>> for Error<(I, usize)>

fn convert(self) -> Error<I>

Transform to another error type

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

fn from_external_error(input: I, kind: ErrorKind, _e: E) -> Self

Create a new error from an input position and an external error

impl<I> ParseError<I> for Error<I>

fn from_error_kind(input: I, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(self, _: I, _: ErrorKind) -> Self

Like ParseError::from_error_kind but merges it with the existing error.

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

Combines errors from two different parse branches.

impl<I: PartialEq> PartialEq<Error<I>> for Error<I>

fn eq(&self, other: &Error<I>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
