Struct Capture 

pub struct Capture {
    pub index: u32,
    pub name: Option<Box<str>>,
    pub sub: Box<Hir>,
}

The high-level intermediate representation for a capturing group.

A capturing group always has an index and a child expression. It may also have a name associated with it (e.g., (?P<foo>\w)), but it’s not necessary.

Note that there is no explicit representation of a non-capturing group in a Hir. Instead, non-capturing grouping is handled automatically by the recursive structure of the Hir itself.

Fields

index: u32

The capture index of the capture.

name: Option<Box<str>>

The name of the capture, if it exists.

sub: Box<Hir>

The expression inside the capturing group, which may be empty.

Trait Implementations

impl Clone for Capture

fn clone(&self) -> Capture

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capture

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

Formats the value using the given formatter.

impl PartialEq for Capture

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