Struct EphemeralMarker 

pub struct EphemeralMarker {
    pub ttl_seconds: u32,
    pub created_at: DateTime<Utc>,
    pub auto_collapse: bool,
}

Ephemeral thread metadata. Lives at the tail of ThreadRecord.

Ephemeral threads are spawned for short-lived agent work that should not crowd heddle log or the thread workspace. If not promoted before ttl_seconds elapses, the thread auto-collapses on the next read-side sweep (heddle status, heddle log, heddle thread list).

Fields

ttl_seconds: u32

Time-to-live, in seconds, measured from ThreadRecord::created_at.

created_at: DateTime<Utc>

When this marker was attached. Usually equal to the thread’s own created_at, but kept separately so a thread can be retroactively marked ephemeral by a later operation if we ever need to.

auto_collapse: bool

When true (the default), the auto-collapse sweep collapses the thread on TTL expiry. Setting false produces a warning at expiry but leaves the thread alive — useful for “ephemeral but I’m not done yet” situations during debugging.

Implementations

impl EphemeralMarker

pub fn new(ttl_seconds: u32) -> Self

pub fn expires_at(&self) -> DateTime<Utc>

Compute the absolute expiry timestamp.

pub fn is_expired_at(&self, now: DateTime<Utc>) -> bool

Whether this marker has expired at the given instant.
