Enum InstanceError 

pub enum InstanceError {
    NotFound,
    Null,
}

An error type returned by FromStatic::instance.

Variants

NotFound

The object’s location wasn’t found in the executable. This usually means something is wrong with the logic of how the object is being loaded in the first place.

Null

The static object is defined, but it’s currently set to null. For many objects, this is a normal occurrence, and just means that the caller should wait until it’s defined to start using it.
