Struct cell_gc::GcRef

pub struct GcRef<'h, T: IntoHeapAllocation<'h>> { /* fields omitted */ }

Methods

impl<'h, T: IntoHeapAllocation<'h>> GcRef<'h, T>

unsafe fn new(p: Pointer<T::In>) -> GcRef<'h, T>

Pin an object, returning a new GcRef that will unpin it when dropped. Unsafe because if p is not a pointer to a live allocation of type T::In --- and a complete allocation, not a sub-object of one --- then later unsafe code will explode.

fn ptr(&self) -> Pointer<T::In>

fn as_ptr(&self) -> *const T::In

fn as_mut_ptr(&self) -> *mut T::In

Trait Implementations

impl<'h, T: IntoHeapAllocation<'h>> Drop for GcRef<'h, T>

fn drop(&mut self)

A method called when the value goes out of scope.

impl<'h, T: IntoHeapAllocation<'h>> Clone for GcRef<'h, T>

fn clone(&self) -> GcRef<'h, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'h, T: IntoHeapAllocation<'h>> PartialEq for GcRef<'h, T>

fn eq(&self, other: &GcRef<'h, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
