pub fn eq<T>(a: *const T, b: *const T) -> bool where
Compare raw pointers for equality.
This is the same as using the
== operator, but less generic:
the arguments have to be
*const T raw pointers,
not anything that implements
This can be used to compare
&T references (which coerce to
*const T implicitly)
by their address rather than comparing the values they point to
(which is what the
PartialEq for &T implementation does).
