Trait std::ptr::RawPtr
pub trait RawPtr<T> {

}Extension methods for raw pointers.
Required Methods
fn null() -> Self
Returns the null pointer.
fn is_null(&self) -> bool
Returns true if the pointer is equal to the null pointer.
fn to_uint(&self) -> uint
Returns the value of this pointer (ie, the address it points to)
unsafe fn to_option(&self) -> Option<&T>
Returns None if the pointer is null, or else returns the value wrapped
in Some.
Safety Notes
While this method is useful for null-safety, it is important to note that this is still an unsafe operation because the returned value could be pointing to invalid memory.
unsafe fn offset(self, count: int) -> Self
Calculates the offset from a pointer. The offset must be in-bounds of
the object, or one-byte-past-the-end. count is in units of T; e.g. a
count of 3 represents a pointer offset of 3 * sizeof::<T>() bytes.
Provided Methods
fn is_not_null(&self) -> bool
Returns true if the pointer is not equal to the null pointer.
