Implementations

impl ErrorKind

pub fn description(&self) -> &str

Converts an ErrorKind to a text description

Trait Implementations

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

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 ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

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

Formats the value using the given formatter.

impl Error for ErrorKind

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<I, E> FromExternalError<I, E> for ErrorKind

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

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

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

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 PartialEq for ErrorKind

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