Modules

app 🔒

Application state and event loop.

backend 🔒

Scheduler-management backend.

cli 🔒

scxtui --cli: scxctl’s command set over the scx.service backend.

kernel 🔒

The kernel’s own view of sched_ext, read straight from sysfs.

logs 🔒

Journal access for the log view.

profiles 🔒

Scheduler profiles (“modes”): named flag sets per scheduler, applied by writing them to SCX_FLAGS next to SCX_SCHEDULER.

ui 🔒

Rendering. Almost a pure function of the App state — the one exception is the log view writing its viewport height and clamped scroll offset back into the app, so paging and bounds always match the actual terminal size.

Structs

App 🔒

Export 🔒

--export-profiles and its options.

Profiles 🔒

The loaded profile set: file contents over built-in defaults.

ServiceBackend 🔒

Enums

ExportFormat 🔒

Output format of --export-profiles.

Invocation 🔒

What the command line asked for besides the TUI.

Constants

USAGE 🔒

Traits

SchedulerBackend 🔒

Common interface of the scheduler-management backend.

Functions

export_profiles 🔒

--export-profiles: the resolved table, as JSON or TOML, to a file or stdout. --builtin needs neither a profiles file nor systemd, so it works on a machine without scx.service; the full export also covers the installed schedulers, which takes the backend.

main 🔒

parse_args 🔒

The informational flags end the process here; everything else is handed back for dispatch after the backend is up.

parse_export 🔒

The options after --export-profiles. The target is the first argument that is not an option, so --export-profiles --builtin writes to stdout and --export-profiles out.toml --format toml to the file; - is stdout explicitly.

replace_file 🔒

Replaces path with text the way the environment file is rewritten: through a scratch file in the same directory and a rename, so that a failure midway leaves the file as it was, and with an existing file’s identity (the file behind a symlink, owner, POSIX access ACL, mode) carried over. A new file is created as File::create would create it, under the umask, which is what the caller’s plain write used to do. For the profile export, whose target is often the live profiles file.
