TreeIOContext

Active context for I/O operations. Keeps track of currently active systems for each I/O interface.

I/O systems are changed by a replace operation. replace takes the new I/O systems, but returns the one set previously. This can be used to manage I/Os as a stack:

auto previous = io.replace(id, this);
scope (exit) io.replace(id, previous);
