Struct ReleaseGuard 

pub struct ReleaseGuard<T> { /* private fields */ }

A wrapper a round a Releasable object that will check, in test and when assertion are enabled, that the value has been released before being dropped.

Implementations

impl<T> ReleaseGuard<T>

pub fn take(this: ReleaseGuard<T>) -> T

Disarm this release guard.

This will prevent any runtime check that the value has been correctly released.

Trait Implementations

impl<T> AsRef<T> for ReleaseGuard<T>

fn as_ref(&self) -> &T

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

impl<T> Borrow<T> for ReleaseGuard<T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: Clone> Clone for ReleaseGuard<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for ReleaseGuard<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for ReleaseGuard<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Deref for ReleaseGuard<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

Converts to this type from the input type.

impl<T: Hash> Hash for ReleaseGuard<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<T: Ord> Ord for ReleaseGuard<T>

fn cmp(&self, other: &ReleaseGuard<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.
