Struct FormationMarker 

pub struct FormationMarker {
    pub project_dir: PathBuf,
    pub launcher_pid: u32,
    pub launcher_start: String,
}

Who launched a formation, from which project: the contents of FORMATION_MARKER_FILE.

The launcher writes it once, before the first peer’s directory is made, and nothing rewrites it. Retention reads it to decide whether a formation directory is this project’s to remove and whether the launcher that made it is still running; a directory without one is never removed.

Fields

project_dir: PathBuf

The roster’s project directory, canonicalized when the launcher could, as given otherwise.

launcher_pid: u32

The launcher’s pid.

launcher_start: String

The launcher’s start token, read as crate::running::process_start_token reads it, or "" when it could not be read.
