Struct cglue::arc::CArc

#[repr(C)]
pub struct CArc<T: Sized + 'static> { /* private fields */ }

FFI-Safe Arc

This is an FFI-Safe equivalent of Arc and Option<Arc>.

Implementations

impl<T> CArc<T>

pub fn take(&mut self) -> CArc<T>

Take arc’s resources, and leave None in its place.

Examples

use cglue::arc::CArc;

let mut arc = CArc::from(0u64);

assert!(arc.as_ref().is_some());

let arc2 = arc.take();

assert!(arc2.as_ref().is_some());
assert!(arc.as_ref().is_none());

pub fn transpose(self) -> Option<CArcSome<T>>

Converts CArc<T> into Option<CArcSome<T>>

Examples

use cglue::arc::{CArc, CArcSome};

let mut arc = CArc::from(0u64);

assert!(arc.as_ref().is_some());

let arc2 = arc.transpose();

assert!(arc2.is_some());
