Struct SessionSweepConfig 

pub struct SessionSweepConfig {
    pub interval: Duration,
    pub tx_warn_secs: Duration,
    pub tx_max_age_secs: Duration,
}

ADR-091 Amendment 2 Plank A: config for the observe-only per-session sweep. Sessions never checkpoint — that stays daemon-owned so N session processes never compete for the writer mutex — this only watches tx_registry (and, Plank B, refreshes this process’s walpin heartbeat).

Fields

interval: Duration

How often a session polls the registry. Coarser than the daemon’s tick: sessions do not need the daemon’s 500ms checkpoint cadence.

Overridable via KHIVE_SESSION_SWEEP_INTERVAL_MS. Default: 5000 ms.

tx_warn_secs: Duration

Same semantics and default as CheckpointConfig::tx_warn_secs.

tx_max_age_secs: Duration

Same semantics and default as CheckpointConfig::tx_max_age_secs.

Implementations

impl SessionSweepConfig

pub fn from_env() -> Self

Build from the environment. Reuses KHIVE_TX_WARN_SECS / KHIVE_TX_MAX_AGE_SECS (the same knobs the daemon’s checkpoint task reads) so a session and the daemon agree on the same thresholds.

Trait Implementations

impl Clone for SessionSweepConfig

fn clone(&self) -> SessionSweepConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionSweepConfig

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

Formats the value using the given formatter.

impl Default for SessionSweepConfig

fn default() -> Self

Returns the “default value” for a type.
