//! Central module dispatch: name → [`WaybarModule::run`] lookup.
|
|
//!
|
|
//! The `dispatch` function is called by the IPC request handler with a module
|
|
//! name (e.g. `"cpu"`, `"vol"`) and returns the rendered [`WaybarOutput`]. All
|
|
//! per-module match arms are generated by [`for_each_watched_module!`];
|
|
//! dispatch-only modules without a watch channel (power/game/btrfs) are
|
|
//! listed manually.
