Struct Group

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

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

pub fn flags(&self) -> Option<&Flags>

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

pub fn is_capturing(&self) -> bool

Returns true if and only if this group is capturing.

pub fn capture_index(&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.

Trait Implementations

impl Clone for Group

fn clone(&self) -> Group

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Group

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

Formats the value using the given formatter.

impl PartialEq for Group

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

impl Eq for Group

impl StructuralPartialEq for Group

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
