Function pre::std::mut_pointer__impl__drop_in_place__ [−][src]
pub fn mut_pointer__impl__drop_in_place__()
Expand description
A stub for the preconditions of the std::mut_pointer<T>::drop_in_place
function.
What is this function?
This function was generated by an impl
block inside a extern_crate
attribute that looked like this:
ⓘ
impl< T > mut_pointer < T > where T : ? Sized {
unsafe fn drop_in_place(self);
/* other items omitted */
}
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 preconditions generated by pre
attributes:
- the pointer
self
must be valid for reads and writes - the pointer
self
must have a proper alignment for its type self
points to a value that is valid for droppingT
isCopy
or the value at*self
isn’t used after this call
To call the function you need to assure
that the preconditions hold:
ⓘ
#[forward(impl pre::std::mut_pointer)]
#[assure(
valid_ptr(self, r+w),
reason = "<specify the reason why you can assure this here>"
)]
#[assure(
proper_align(self),
reason = "<specify the reason why you can assure this here>"
)]
#[assure(
"`self` points to a value that is valid for dropping",
reason = "<specify the reason why you can assure this here>"
)]
#[assure(
"`T` is `Copy` or the value at `*self` isn't used after this call",
reason = "<specify the reason why you can assure this here>"
)]
x.drop_in_place(/* parameters omitted */);
