# description Short, lowercase identifier for the current case. ``` var description: String { get } ``` ## Return Value `"idle"`, `"starting"`, `"running"`, `"stopping"`, `"stopped"`, or `"failed()"`. ## Discussion Intended for log lines and human-readable UI labels. The string returned is stable across releases and matches the case name; for `.failed(_)` it wraps the associated [`TorError`](/documentation/Tor/TorError)’s `CustomStringConvertible` form inside `"failed(…)"` to keep the causal information visible at a glance.
