Struct winnow::error::InputError

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

Capture input on error

This is useful for testing of generic parsers to ensure the error happens at the right location.

Note: context and inner errors (like from Parser::try_map) 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: Clone> InputError<I>

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

Creates a new basic error

pub fn map_input<I2: Clone, O: Fn(I) -> I2>(self, op: O) -> InputError<I2>

Translate the input type

impl<'i, I: ToOwned> InputError<&'i I>

where <I as ToOwned>::Owned: Clone,

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

Available on crate feature alloc only.

Obtaining ownership

Trait Implementations

impl<I: Stream + Clone, C> AddContext<I, C> for InputError<I>

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

Append to an existing error custom data

impl<I: Clone + Clone> Clone for InputError<I>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Debug + Clone> Debug for InputError<I>

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

Formats the value using the given formatter.

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

Available on crate feature std only.

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, 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<I: Clone> ErrorConvert<InputError<(I, usize)>> for InputError<I>

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

Transform to another error type

impl<I: Clone> ErrorConvert<InputError<I>> for InputError<(I, usize)>

fn convert(self) -> InputError<I>

Transform to another error type

impl<I: Clone, E> FromExternalError<I, E> for InputError<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: Clone + Stream> FromRecoverableError<I, InputError<I>> for InputError<I>

Available on crate feature unstable-recover only.

fn from_recoverable_error( _token_start: &<I as Stream>::Checkpoint, _err_start: &<I as Stream>::Checkpoint, _input: &I, e: Self ) -> Self

Capture context from when an error was recovered

impl<I: Stream + Clone> ParserError<I> for InputError<I>

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

Creates an error from the input position and an ErrorKind

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

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

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

where I: Debug,

Process a parser assertion

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

Combines errors from two different parse branches.

impl<I: PartialEq + Clone> PartialEq for InputError<I>

fn eq(&self, other: &InputError<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.
