An error that occurred during regex compilation or matching.

Implementations

impl Error

pub fn syntax( pattern: &str, position: usize, message: impl Into<String>, ) -> Self

Create a new syntax error.

pub fn unsupported(feature: impl Into<String>) -> Self

Create a new unsupported feature error.

pub fn compile(message: impl Into<String>) -> Self

Create a new compilation error.

pub fn too_complex(message: impl Into<String>) -> Self

Create a new error for patterns that are too complex.

pub fn execution_limit(message: impl Into<String>) -> Self

Create a new error for execution limit exceeded (ReDoS protection).

pub fn kind(&self) -> &ErrorKind

Returns the kind of error.

pub fn pattern(&self) -> Option<&str>

Returns the pattern that caused the error, if available.

pub fn position(&self) -> Option<usize>

Returns the position in the pattern where the error occurred.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
