Struct `Group`

struct Group { ... }

A grouped regular expression.

This includes both capturing and non-capturing groups. This does not include flag-only groups like (?is), but does contain any group that contains a sub-expression, e.g., (a), (?P<name>a), (?:a) and (?is:a).

Fields

span: Span: The span of this group.
kind: GroupKind: The kind of this group.
ast: Box<Ast>: The regular expression in this group.

Implementations

`impl Group`

fn flags(self: &Self) -> Option<&Flags>

If this group is non-capturing, then this returns the (possibly empty) set of flags. Otherwise, None is returned.

fn is_capturing(self: &Self) -> bool

Returns true if and only if this group is capturing.

fn capture_index(self: &Self) -> Option<u32>

Returns the capture index of this group, if this is a capturing group.

This returns a capture index precisely when is_capturing is true.
