Struct rs::util::c::Wrapped

#[repr(transparent)]
pub struct Wrapped<T>(*const RefCell<T>);

Wraps structures to pass them safely to/from C Since C doesn’t respect borrowing rules, RefCell will enforce them dynamically (only 1 writer/many readers) Rc is implied and will ensure timely dropping

Tuple Fields

0: *const RefCell<T>

Implementations

impl<T> Wrapped<T>

pub fn new(value: T) -> Wrapped<T>

pub fn wrap(state: Rc<RefCell<T>>) -> Wrapped<T>

pub unsafe fn unwrap(self) -> Rc<RefCell<T>>

Extracts the reference to the data. It may cause problems if attempted in more than one place

pub fn clone_ref(&self) -> Rc<RefCell<T>>

Creates a new Rc reference to the same data. Use for accessing the underlying data as a reference.

Trait Implementations

impl<T> Clone for Wrapped<T>

fn clone(&self) -> Wrapped<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Clone> CloneOwned for Wrapped<T>

ToOwned won’t work here because it’s really difficult to implement Borrow on Wrapped with the Rc<RefCell<>> chain on the way to the data

type Owned = T

fn clone_owned(&self) -> T

impl<T> COpaquePtr for Wrapped<T>
