fn push_match(&mut self, idx: usize, m: NamedMatch)

Adds m as a named match for the idx-th metavar.

Trait Implementations

impl<'root, 'tt> Clone for MatcherPosHandle<'root, 'tt>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'root, 'tt> Deref for MatcherPosHandle<'root, 'tt>

type Target = MatcherPos<'root, 'tt>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'root, 'tt> DerefMut for MatcherPosHandle<'root, 'tt>

fn deref_mut(&mut self) -> &mut MatcherPos<'root, 'tt>

Mutably dereferences the value.

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.
