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

Available on crate feature std only.

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.

impl Copy for ErrorKind

impl Eq for ErrorKind

impl StructuralPartialEq for ErrorKind

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
