Trait Implementations

impl<T, U> AsMut<T> for MetaRefMut<'_, T, U>

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a, T, U> AsRef<MetaRef<'a, T>> for MetaRefMut<'a, T, U>

fn as_ref(&self) -> &MetaRef<'a, T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, T: Debug + 'a, U> Debug for MetaRefMut<'a, T, U>

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

Formats the value using the given formatter.

impl<T, U> Deref for MetaRefMut<'_, T, U>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T, U> DerefMut for MetaRefMut<'_, T, U>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.
