Required Methods

fn label(&self) -> String

Short description for the header line.

fn list(&self) -> Result<Listing>

scxcli list --json.

fn start(&self, id: &str) -> Result<String>

scxcli start ID: default, or a scheduler by name with its defaults. Returns scxcli’s one-line report; the state comes back through Self::list.

fn run(&self, sched: &str, args: &[String]) -> Result<String>

scxcli run SCHED ARGS....

fn stop(&self) -> Result<String>

scxcli stop: the unit stops, the selection stays.

fn escalates(&self) -> bool

Whether the privileged commands go through pkexec, which may prompt on the terminal and so needs it handed over.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
