Enum SessionLiveness 

pub enum SessionLiveness {
    Alive,
    Stale,
    Indeterminate,
}

Outcome of a session-liveness probe (design D3 of session-bugfixes).

Distinguishes a genuinely-absent tmux session (Stale) from a probe that could not be run at all (Indeterminate, e.g. the tmux binary is missing). Receipt-staleness detection SHALL NOT report 🔴 stale on an Indeterminate probe — a missing tmux binary is not evidence the session died.

Variants

Alive

tmux has-session returned exit 0 — the session exists.

Stale

tmux has-session ran and returned non-zero — the session is gone.

Indeterminate

The probe could not be run (tmux binary absent/unreachable). The caller SHALL preserve the receipt’s current state.

Trait Implementations

impl Clone for SessionLiveness

fn clone(&self) -> SessionLiveness

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SessionLiveness

impl Debug for SessionLiveness

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

Formats the value using the given formatter.

impl Eq for SessionLiveness

impl PartialEq for SessionLiveness

fn eq(&self, other: &SessionLiveness) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
