Function pre::core::ptr::read_unaligned [−][src]
pub unsafe fn read_unaligned<T>(src: *const T) -> T
Expand description
core::ptr::read_unaligned
with preconditions.
This function behaves exactly like core::ptr::read_unaligned
, but also has preconditions checked by pre
.
You should also read the Safety section on the documentation of core::ptr::read_unaligned
.
This function has preconditions
This function has the following preconditions generated by pre
attributes:
- the pointer
src
must be valid for reads src
points to a properly initialized value of typeT
T
isCopy
or the value at*src
isn’t used after this call
To call the function you need to assure
that the preconditions hold:
ⓘ
#[assure(
valid_ptr(src, r),
reason = "<specify the reason why you can assure this here>"
)]
#[assure(
"`src` points to a properly initialized value of type `T`",
reason = "<specify the reason why you can assure this here>"
)]
#[assure(
"`T` is `Copy` or the value at `*src` isn't used after this call",
reason = "<specify the reason why you can assure this here>"
)]
