pub struct WriteOnly<'s, T: ?Sized + 's>(/* private fields */);
Expand description
Pointer type which can only be written to.
Implementations§
source§impl<'s, T: ?Sized> WriteOnly<'s, T>
impl<'s, T: ?Sized> WriteOnly<'s, T>
sourcepub unsafe fn new(t: *mut T) -> WriteOnly<'s, T>
pub unsafe fn new(t: *mut T) -> WriteOnly<'s, T>
Unsafe as the lifetime must not be longer than the liftime of t
sourcepub fn as_mut_ptr(&mut self) -> *mut T
pub fn as_mut_ptr(&mut self) -> *mut T
Retrieves the pointer allowing it to be manipulated freely. As it points to uninitialized data care must be taken so to not read it before it has been initialized
