Struct with_drop::WithDrop

pub struct WithDrop<T, F: FnOnce(T)> { /* fields omitted */ }

Container that holds a value and a customestructor

Implementations

impl<T, F: FnOnce(T)> WithDrop<T, F>

pub fn new(inner: T, drop_fn: F) -> Self

pub fn into_inner(self) -> T

This extracts the contained value while dropping the closure and the container.

The custom closure will not be executed.

Trait Implementations

impl<T: Clone, F: Clone + FnOnce(T)> Clone for WithDrop<T, F>

fn clone(&self) -> WithDrop<T, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, F: Debug + FnOnce(T)> Debug for WithDrop<T, F>

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

Formats the value using the given formatter.

impl<T, F: FnOnce(T)> Deref for WithDrop<T, F>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T, F: FnOnce(T)> DerefMut for WithDrop<T, F>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T, F: FnOnce(T)> Drop for WithDrop<T, F>

impl<T: Eq, F: Eq + FnOnce(T)> Eq for WithDrop<T, F>

impl<T: Ord, F: Ord + FnOnce(T)> Ord for WithDrop<T, F>

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl<T: PartialEq<T>, F1: FnOnce(T), F2: FnOnce(T)> PartialEq<WithDrop<T, F2>> for WithDrop<T, F1>

fn eq(&self, other: &WithDrop<T, F2>) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<T: PartialOrd<T>, F1: FnOnce(T), F2: FnOnce(T)> PartialOrd<WithDrop<T, F2>> for WithDrop<T, F1>

fn partial_cmp(&self, other: &WithDrop<T, F2>) -> Option<Ordering>

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

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