Struct OwnedEntry 

pub struct OwnedEntry<T: Default> { /* private fields */ }

An owned entry in the pool.

OwnedEntry holds a reference pointer to an item from the pool and a Arc reference to the Pool. When the last OwnedEntry is dropped, the item is returned to the pool.

Implementations

impl<T: Default> OwnedEntry<T>

pub fn get(&self) -> &T

Get reference to the inner item.

pub fn get_mut(&mut self) -> Option<&mut T>

Get mutable reference to the inner item if there are no other references. Otherwise, return None.

pub unsafe fn get_mut_unchecked(&mut self) -> &mut T

Get mutable reference to the inner item without checking for other references.

Trait Implementations

impl<T: Default> Clone for OwnedEntry<T>

fn clone(&self) -> Self

Makes a clone of the OwnedEntry that points to the same allocation.

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

Performs copy-assignment from source.

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

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T: Default> Drop for OwnedEntry<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Default + Hash> Hash for OwnedEntry<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,

Feeds a slice of this type into the given Hasher.

impl<T: Default + Ord> Ord for OwnedEntry<T>

fn cmp(&self, other: &Self) -> Ordering

Comparison for two OwnedEntry

Example

use concurrent_pool::Pool;
use std::sync::Arc;

let pool = Arc::new(Pool::<usize>::with_capacity(2));
let item1 = pool.pull_owned_with(|i| *i = 1).unwrap();
let item2 = pool.pull_owned_with(|i| *i = 2).unwrap();
assert!(item1 < item2);

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.

impl<T: Default + PartialEq> PartialEq for OwnedEntry<T>

fn eq(&self, other: &Self) -> 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: Default + PartialOrd> PartialOrd for OwnedEntry<T>

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

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

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

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

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

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: Default + Serialize> Serialize for OwnedEntry<T>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Default + Eq> Eq for OwnedEntry<T>
