Enum GroupKind 

pub enum GroupKind {
    Capturing,
    Named(String),
    NonCapturing,
    LookaheadPos,
    LookaheadNeg,
    LookbehindPos,
    LookbehindNeg,
}

How a group should be treated by a regex engine.

Variants

Capturing

Plain (...) — captures and numbers the match.

Named(String)

(?P<name>...) — captures with a name.

NonCapturing

(?:...) — groups without capturing.

LookaheadPos

(?=...) — positive lookahead.

LookaheadNeg

(?!...) — negative lookahead.

LookbehindPos

(?<=...) — positive lookbehind.

LookbehindNeg

(?<!...) — negative lookbehind.

Trait Implementations

impl Clone for GroupKind

fn clone(&self) -> GroupKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupKind

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

Formats the value using the given formatter.

impl PartialEq for GroupKind

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