Enum Error

#[non_exhaustive]
pub enum Error {
    ParseError(usize, ParseError),
    CompileError(CompileError),
    RuntimeError(RuntimeError),
}

An error as the result of parsing, compiling or running a regex.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ParseError(usize, ParseError)

An error as a result of parsing a regex pattern, with the position where the error occurred

CompileError(CompileError)

An error as a result of compiling a regex

RuntimeError(RuntimeError)

An error as a result of running a regex

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy 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.

impl From<CompileError> for Error

fn from(compile_error: CompileError) -> Self

Converts to this type from the input type.
