Struct arret_runtime::boxed::refs::Gc

#[repr(transparent)]
pub struct Gc<T: Boxed> { /* fields omitted */ }

Reference to a garbage collected value

This is not memory safe and does not GC root; it’s just sugar for a raw pointer.

Implementations

impl<T: Boxed> Gc<T>

pub unsafe fn new(ptr: *const T) -> Gc<T>

Returns a new instance wrapping a pointer to a garbage collected box

Safety

The requires a valid pointer to a box

pub unsafe fn cast<U: Boxed>(self) -> Gc<U>

Unchecked cast to the passed type

Safety

The requires the box to be of the asserted type

pub fn as_ptr(self) -> *const T

Returns a pointer to the garbage collected box
