Struct PassableContainer 

Source 
pub struct PassableContainer<PTR, PAS: Passable<PTR>> { /* private fields */ }
Expand description

A Container that allows for checked passing of a pointer over a FFI boundary

Implementations§

Source§

impl<PTR, PAS: Passable<PTR>> PassableContainer<PTR, PAS>

Source

pub fn new(passable: PAS) -> Self

Creates a new PassableContainer from a Passable

Source

pub fn into_inner(self) -> PAS

Get back the Passable from this Container

Source

pub fn pass(self) -> (PassableGuard<PTR, PAS>, *mut PTR)

Convert the PassableContainer into a pointer to pass it over a FFI boundary

Source

pub unsafe fn pass_unguarded(self) -> *mut PTR

Convert the PassableContainer into a pointer to pass if over a FFI Boundary

§Unsafe

Since this does not create a PassableGuard to accompany the pointer, it is unsafe
