Struct RepeatableTryDropAdapter 

pub struct RepeatableTryDropAdapter<T: PureTryDrop> {
    pub inner: T,
    /* private fields */
}

This type is an adapter for types which implement TryDrop which allow their TryDrop::try_drop functions to be repeated multiple times.

Fields

inner: T

The inner value.

impl<T: Ord + PureTryDrop> Ord for RepeatableTryDropAdapter<T>

fn cmp(&self, other: &RepeatableTryDropAdapter<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.

Restrict a value to a certain interval.

impl<T: PartialEq + PureTryDrop> PartialEq for RepeatableTryDropAdapter<T>

fn eq(&self, other: &RepeatableTryDropAdapter<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: PartialOrd + PureTryDrop> PartialOrd for RepeatableTryDropAdapter<T>

fn partial_cmp(&self, other: &RepeatableTryDropAdapter<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T: PureTryDrop> PureTryDrop for RepeatableTryDropAdapter<T>

type Error = <T as PureTryDrop>::Error

The type of the error that may occur during drop.

type FallbackTryDropStrategy = <T as PureTryDrop>::FallbackTryDropStrategy

The type which will be used if the drop strategy fails.

type TryDropStrategy = <T as PureTryDrop>::TryDropStrategy

The type which will be used if dropping fails.

fn fallback_try_drop_strategy(&self) -> &Self::FallbackTryDropStrategy

Get a reference to the fallback try drop strategy.

fn try_drop_strategy(&self) -> &Self::TryDropStrategy

Get a reference to the try drop strategy.

unsafe fn try_drop(&mut self) -> Result<(), Self::Error>

Execute the fallible destructor for this type. This function is unsafe because if this is called outside of a Drop::drop context, once the scope of the object implementing trait ends, this function will be called twice, potentially resulting in a double-free.

fn adapt(self) -> DropAdapter<Self>

where Self: Sized,

Adapts this type to take advantage of the specified try drop strategies.

impl<T: PureTryDrop> RepeatableTryDrop for RepeatableTryDropAdapter<T>

fn safe_try_drop(&mut self) -> Result<(), Self::Error>
