Trait Implementations

impl<Input: Clone> Clone for Error<Input>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Input: Debug> Debug for Error<Input>

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

Formats the value using the given formatter.

impl<Input> Display for Error<Input>

where Input: Display,

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

Formats the value using the given formatter.

impl<Input> Error for Error<Input>

where Error<Input>: Debug + Display,

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<Input> From<Error<Input>> for Error<Input>

Available on crate feature into-regex only.

fn from(value: Error<Input>) -> Self

Converts to this type from the input type.

impl<Input> ParseError<Input> for Error<Input>

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

Creates an error from the input position and an ErrorKind

fn append(input: Input, kind: ErrorKind, other: Self) -> Self

Combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(input: I, _: char) -> Self

Creates an error from an input position and an expected character

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

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

impl<Input: PartialEq> PartialEq for Error<Input>

fn eq(&self, other: &Error<Input>) -> 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<Input: Copy> Copy for Error<Input>

impl<Input: Eq> Eq for Error<Input>

impl<Input> StructuralPartialEq for Error<Input>
