Trait supercow::ext::PtrWrite
[−]
[src]
pub unsafe trait PtrWrite<T: ?Sized>: Copy { fn new() -> Self; fn store_ptr(&mut self, t: *const T); }
Optionally stores a pointer to a value.
It is doubtful that there are any types besides () and *mut T which
could implement this usefully.
Required Methods
fn new() -> Self
Returns an instance of Self with no particular value.
fn store_ptr(&mut self, t: *const T)
Writes the given pointer into self.
Unsafety
The implementation must not inspect the given pointer. This call must not panic.
