fn or<E>(self, e: E) -> Or<Self, E> where
    Self: Sized,
    E: Endpoint<Item = Self::Item, Error = Self::Error>, 

Create an endpoint which attempts to apply self. If self failes, then revert the context and retry applying e.

fn map<F, U>(self, f: F) -> Map<Self, F> where
    Self: Sized,
    F: FnOnce(Self::Item) -> U, 

Combine itself and a function to change the return value to another type.
