PossessorNone

PossessorNone is a concept in programming used in the Rust language's ownership system. It indicates that a variable or reference does not currently possess ownership or control over a resource, such as memory or data. When you see PossessorNone, it means the variable isn't managing any resource at that moment, making it safe to assign or transfer ownership elsewhere. This helps prevent issues like double-free errors or data races, ensuring safe and efficient memory management by explicitly signaling when a resource is not owned or is available for reassignment.
