Struct RcUninit

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

Defer initialization of Rc while providing Weak pointers to the allocation.

Implementations

impl<T> RcUninit<T>

pub fn new() -> Self

Creates a new RcUninit.

Panics

Panics if check_sanity has not been called at least once.

Examples

use rcuninit::RcUninit;
unsafe {
    rcuninit::check_sanity();
}
RcUninit::<i32>::new();

pub fn weak(&self) -> Weak<T>

Returns a Weak pointer that cannot be upgraded until RcUninit::init is called.

Examples

use rcuninit::RcUninit;
use std::rc::Weak;

unsafe {
    rcuninit::check_sanity();
}

let uninit = RcUninit::<i32>::new();
let weak: Weak<i32> = uninit.weak();

pub fn init(self, value: T) -> Rc<T>

Initializes the pointer.

Examples

use rcuninit::RcUninit;
use std::rc::Rc;

unsafe {
    rcuninit::check_sanity();
}

let uninit = RcUninit::new();
let rc: Rc<i32> = uninit.init(123);

Trait Implementations

impl<T> Default for RcUninit<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Drop for RcUninit<T>

fn drop(&mut self)

Executes the destructor for this type.
