Package meta

Synopsis

Monitor groups of threads with non-hierarchical lifetimes.

Description

The supervisors package provides a useful abstraction for managing the groups of Haskell threads, which may not have a strictly hierarchical structure to their lifetimes.

Concretely, the library provides a Supervisor construct, which can be used to safely spawn threads while guaranteeing that:

• When the supervisor is killed, all of the threads it supervises will be killed.

• Child threads can terminate in any order, and memory usage will always be proportional to the number of *live* supervised threads.

One way to think of it is that supervisors is to async as resourcet is to bracket.

Note that this package is EXPERIMENTAL; it needs more careful testing before I can earnestly recommend relying on it.

See the README and module documentation for more information.
