Function pre::std::mem::ManuallyDrop__impl__drop__ [−][src]
pub fn ManuallyDrop__impl__drop__()
Expand description
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:
ⓘ
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:
ⓘ
#[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 */);
