TopicPath

public struct TopicPath : Hashable, CustomStringConvertible, ExpressibleByArrayLiteral

An abstract path for log events.

This is used to provide a simple hierarchical structure to log events to facilitate filtering and collapsing, mostly by Features but also arbitrary paths for non-Feature based subsystems.
