Enum RegexParseError 

pub enum RegexParseError {
    UnterminatedCaptureGroup,
    UnterminatedCharSet,
    InvalidEscapedChar(char),
    InvalidAtom(char),
    UnexpectedEOF,
}

Variants

UnterminatedCaptureGroup

A capture group (e.g. (abc)) was unterminated

UnterminatedCharSet

A character class set (e.g. [a-z]) was unterminated

InvalidEscapedChar(char)

An escaped symbol was invalid.

InvalidAtom(char)

UnexpectedEOF

Should only happen in debug settings, since it happens only when we call Atom::take("")

Trait Implementations

impl Debug for RegexParseError

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

Formats the value using the given formatter.

impl Display for RegexParseError

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

Formats the value using the given formatter.

impl Error for RegexParseError

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 PartialEq for RegexParseError

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