pub struct Versions {
    pub dir: PathBuf,
}

$SUPERFLUID_HOME/versions: a directory per release, current, previous, and prefix naming the bin directory that links here.

Fields

dir: PathBuf

Implementations

impl Versions

pub fn of(home: &Path) -> Versions

pub fn version_dir(&self, v: &str) -> PathBuf

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

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

pub fn on_disk(&self) -> Vec<String>

The complete versions here, newest first.

pub fn prefix(&self) -> Option<PathBuf>

pub fn set_current(&self, v: &str) -> Result<(), String>

Point current at v, atomically, remembering what it pointed at.

pub fn prune(&self) -> Result<Vec<String>, String>

Removes every version but current, previous, one with a keep file, and one a running process started from.

pub fn link( &self, prefix: &Path, replace_files: bool, ) -> Result<Vec<String>, String>

The links in prefix: the three commands through current, and superfluid-<v> per version. The install script’s real files are replaced on a migration, except superfluid-workerd while a server still runs from it (it starts its workers by that path), which a migrating note has the next link finish once nothing runs from there. The note names the processes that ran from there, by pid and start time: once a link is renamed over a server’s own executable, macOS may give no path for it, and a server found by its path alone would be missed.
