Struct MutGuard

pub struct MutGuard<'a, V, S = &'a mut KvSize>
where
    V: EstimateSize,
    S: GenericKvSize,
{
    inner: &'a mut V,
    original_val_size: usize,
    total_size: S,
}

A guard holding a mutable reference to a value in a collection. When dropped, the size of the collection will be updated.

Fields

inner: &'a mut V

original_val_size: usize

total_size: S

Implementations

impl<'a, V, S> MutGuard<'a, V, S>

where V: EstimateSize, S: GenericKvSize,

pub fn new(inner: &'a mut V, total_size: S) -> Self

Trait Implementations

impl<V, S> Deref for MutGuard<'_, V, S>

where V: EstimateSize, S: GenericKvSize,

type Target = V

The resulting type after dereferencing.

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

Dereferences the value.

impl<V, S> DerefMut for MutGuard<'_, V, S>

where V: EstimateSize, S: GenericKvSize,

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

Mutably dereferences the value.

impl<V, S> Drop for MutGuard<'_, V, S>

where V: EstimateSize, S: GenericKvSize,

fn drop(&mut self)

Executes the destructor for this type.
