Function core::ptr::read_and_zero
[−]
[src]
pub unsafe fn read_and_zero<T>(dest: *mut T) -> T
Deprecated since 1.3.0
: a "zero value" will soon not actually exist for all types once dynamic drop has been implemented
Reads the value from src
`src` and nulls it out without dropping it.
Safety
This is unsafe for the same reasons that read
`read` is unsafe.
