[][src]Struct crossbeam::epoch::Owned

pub struct Owned<T> { /* fields omitted */ }

An owned heap-allocated object.

This type is very similar to Box<T>.

The pointer must be properly aligned. Since it is aligned, a tag can be stored into the unused least significant bits of the address.

Methods

impl<T> Owned<T>[src]

pub fn new(value: T) -> Owned<T>[src]

Allocates value on the heap and returns a new owned pointer pointing to it.

Examples

use crossbeam_epoch::Owned;

let o = Owned::new(1234);

pub unsafe fn from_raw(raw: *mut T) -> Owned<T>[src]

Returns a new owned pointer pointing to raw.

This function is unsafe because improper use may lead to memory problems. Argument raw must be a valid pointer. Also, a double-free may occur if the function is called twice on the same raw pointer.

Panics

Panics if raw is not properly aligned.

Examples

use crossbeam_epoch::Owned;

let o = unsafe { Owned::from_raw(Box::into_raw(Box::new(1234))) };

pub fn into_shared(self, &'g Guard) -> Shared<'g, T>[src]

Converts the owned pointer into a Shared.

Examples

use crossbeam_epoch::{self as epoch, Owned};

let o = Owned::new(1234);
let guard = &epoch::pin();
let p = o.into_shared(guard);

pub fn into_box(self) -> Box<T>[src]

Converts the owned pointer into a Box.

Examples

use crossbeam_epoch::{self as epoch, Owned};

let o = Owned::new(1234);
let b: Box<i32> = o.into_box();
assert_eq!(*b, 1234);

pub fn tag(&self) -> usize[src]

Returns the tag stored within the pointer.

Examples

use crossbeam_epoch::Owned;

assert_eq!(Owned::new(1234).tag(), 0);

pub fn with_tag(self, tag: usize) -> Owned<T>[src]

Returns the same pointer, but tagged with tag. tag is truncated to be fit into the unused bits of the pointer to T.

Examples

use crossbeam_epoch::Owned;

let o = Owned::new(0u64);
assert_eq!(o.tag(), 0);
let o = o.with_tag(2);
assert_eq!(o.tag(), 2);
