impl AsRef<AllStorages> for AllStoragesViewMut<'_>

fn as_ref(&self) -> &AllStorages

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

impl<'a> BorrowInfo for AllStoragesViewMut<'a>

fn borrow_info(info: &mut Vec<TypeInfo>)

This information is used during workload creation to determine which systems can run in parallel.

fn enable_tracking(_: &mut Vec<fn(&AllStorages) -> Result<(), GetStorage>>)

impl Deref for AllStoragesViewMut<'_>

type Target = AllStorages

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for AllStoragesViewMut<'_>

fn deref_mut(&mut self) -> &mut Self::Target
