Async::Container SourceAsyncContainerKeyed

class Keyed

Tracks a key/value pair such that unmarked keys can be identified and cleaned up. This helps implement persistent processes that start up child processes per directory or configuration file. If those directories and/or configuration files are removed, the child process can then be cleaned up automatically, because those key/value pairs will not be marked when reloading the container.
