Struct RuntimeDir 

pub struct RuntimeDir { /* private fields */ }

One session’s runtime directory, from its creation at staging to its removal when the value is dropped.

Implementations

impl RuntimeDir

pub fn create( sessions_path: &Path, session_id: &str, latch_of: &WorkdirRoot, ) -> Result<Self, String>

Creates <sessions_path>/<session_id>/, locks it, sweeps stale siblings and creates runtime/, sealed-etc/ and harness/ beneath it at 0700. Every refusal beneath the three lands on latch_of’s latch and names its path absolutely.

sessions_path is sessions_dir’s answer, the one the launch was judged against. The murmur home is held through crate::murmur_home::ensure_murmur_home first.

pub fn path(&self) -> &Path

runtime/’s absolute path, the value of $MURMUR_RUNTIME_DIR.

pub fn roots(&self) -> &RuntimeDirRoots

The three held directories.

Trait Implementations

impl Debug for RuntimeDir

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for RuntimeDir

fn drop(&mut self)

Removes <session-id>/ by descriptor from the held sessions/, before the lock is released, so no sweep can race the removal.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
