[−][src]Function pre::std::mem::ManuallyDrop__impl__drop__
pub fn ManuallyDrop__impl__drop__()
A stub for the preconditions of the std::mem::ManuallyDrop<T>::drop
function.
What is this function?
This function was generated by an impl
block inside a extern_crate
attribute that looked like this:
ⓘThis example is not tested
impl< T : ? Sized > ManuallyDrop < T > { unsafe fn drop(slot : & mut ManuallyDrop < T >); }
Preconditions on external functions inside of an impl
block are attached to empty functions like this one.
When the preconditions should be checked, a call to this function is inserted, which triggers checking the preconditions.
This function has preconditions
This function has the following precondition generated by the pre
attribute:
- this
ManuallyDrop
is not used again after this call
To call the function you need to assure
that the precondition holds:
ⓘThis example is not tested
#[forward(impl pre::std::mem::ManuallyDrop)] #[assure( "this `ManuallyDrop` is not used again after this call", reason = "<specify the reason why you can assure this here>" )] drop(/* parameters omitted */);
