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 copy 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.

impl Eq for Capture

impl StructuralPartialEq for Capture

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.
