Struct high_mem_utils::DontDrop

#[repr(transparent)]
pub struct DontDrop<T: Default>(pub T);

Deprecated since 0.2.4:

Use ManuallyDrop or DontDropOpt if you want to take the value and reuse the container,instead.

A wrapper for an implementation of drop that mem::take the value and mem::forgets it.

This might be useful if you want assuring that a particular destructor not run if it can lead to a double-free or another memory issue.

This type is particularly not recomended for reference types because as such they can never be null and the value is still dropped. Neither on types with a costly initialization because it replaces the forgotten value with the Default one,these values should not implement it anyways.

This type has the same implications that forget except for the fact that this ensures that the value is never dropped even on panic,unless you abort.In general DontDropOpt is preferred.

It derefs to T.

Methods

impl<T: Default> DontDrop<T>

pub fn into_inner(&mut self) -> T

Returns the field,allowing it to be dropped again.

Trait Implementations

impl<T: Default> Deref for DontDrop<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: Default> DerefMut for DontDrop<T>

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

Mutably dereferences the value.

impl<T: Default> Drop for DontDrop<T>

fn drop(&mut self)

Executes the destructor for this type.
