clone_into_box

Trait CloneIntoBox

Source 
pub trait CloneIntoBox {
    // Required method
    unsafe fn clone_into_ptr(&self, ptr: *mut u8);
}
Expand description

A (possibly unsized) value which can be cloned into a pre-allocated space.

Users can use CloneIntoBoxExt to clone it into Box<T>.

Required Methods§

Source

unsafe fn clone_into_ptr(&self, ptr: *mut u8)

Clone into the specified place.

§Effect

After successful invocation, the area pointed to by ptr will contain a valid representation of Self with auxiliary data contained in the self fat pointer.

§Safety

The ptr parameter must point to an uninitialized area which has enough space of std::mem::size_of_val(self) bytes and is aligned to std::mem::align_of_val(self) bytes.

§Panics

This method isn’t expected to panic in normal cases, but the caller must handle panics carefully for safety.
