pub struct Group {
    pub span: Span,
    pub kind: GroupKind,
    pub ast: Box<Ast>,
}
Expand description

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

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

Returns true if and only if this group is capturing.

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

This returns a capture index precisely when is_capturing is true.
