Trait Successor 

pub trait Successor {
    // Provided method
    fn successor(&self) -> Option<Self>
       where Self: Sized { ... }
}

A successor is a term that comes right after a particular value. Suppose n is a number (where n belongs to any whole number), then the successor of n is ‘n+1’. The other terminologies used for a successor are just after, immediately after, and next value.

Provided Methods

fn successor(&self) -> Option<Self>

where Self: Sized,

Returns the successor of the current value if it exists, otherwise returns None.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
