Struct ScxcliBackend 

pub(crate) struct ScxcliBackend {
    root: bool,
    scxcli: PathBuf,
}

Fields

root: bool

scxcli: PathBuf

The absolute path scxcli resolved to, passed as such to pkexec: polkit matches the action on the program’s path, so the name is resolved here, once, in the trusted search path, not by pkexec against whatever PATH it has.

Implementations

impl ScxcliBackend

pub fn connect() -> Result<Self>

Checks that scxcli is installed, so startup fails fast with a plain message instead of the first key press.

pub fn policy_mismatch(&self) -> Option<String>

A warning for startup when scxcli is not where the policy expects it, since every privileged action then prompts.

fn privileged(&self, args: &[&str]) -> Result<Command>

A privileged scxcli command: direct as root, else via pkexec. Both are resolved in systemd’s default search path, not scxtui’s PATH.

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

Trait Implementations

impl Backend for ScxcliBackend

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.
