enum Ref<'a> {
    Named(&'a str),
    Number(usize),
}

A reference to a capture group in some text.

e.g., $2, $foo, ${foo}.

Variants

Named(&'a str)

Number(usize)

Trait Implementations

impl<'a> Clone for Ref<'a>

fn clone(&self) -> Ref<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Ref<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for Ref<'a>

fn from(x: &'a str) -> Ref<'a>

Converts to this type from the input type.

impl From<usize> for Ref<'static>

fn from(x: usize) -> Ref<'static>

Converts to this type from the input type.

impl<'a> PartialEq for Ref<'a>

fn eq(&self, other: &Ref<'a>) -> 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.
