Struct cfx_storage :: utils :: guarded_value :: GuardedValue Copy item path

impl<GuardType, ValueType> GuardedValue<GuardType, ValueType>

pub fn new(guard: GuardType, value: ValueType) -> Self

pub fn into(self) -> (GuardType, ValueType)

It’s unsafe to drop the returned guard manually, or to clone the ValueType. Extra care is needed when using this method.

Trait Implementations§

impl<GuardType, ValueType> AsMut<ValueType> for GuardedValue<GuardType, ValueType>

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

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

impl<GuardType, ValueType> AsRef<ValueType> for GuardedValue<GuardType, ValueType>

fn as_ref(&self) -> &ValueType

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

impl<GuardType, ValueType: DerefMut> DerefMut for GuardedValue<GuardType, ValueType>

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

Mutably dereferences the value.

impl<GuardType, ValueType: Deref> Deref for GuardedValue<GuardType, ValueType>

It’s safer to directly deref to the next level target, because when the ValueType is &’a Target, when we deref twice, we get &‘a Target, when we deref to the next level we always get the expected &’_ Target.

type Target = <ValueType as Deref>::Target

The resulting type after dereferencing.

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

Dereferences the value.
