Type Alias Session 

type Session<'a, 'b, T, CB> = Session<'a, 'b, T, CB, Capability<T>>;

Type alias for a timely output Session whose capability is a Capability<T>. The container builder CB is left to the caller; sessions can therefore drive consolidating, capacity, or (in the future) columnar output builders without changing call sites.

Aliased Type

struct Session<'a, 'b, T, CB> { /* private fields */ }
