Struct RunId 

pub struct RunId(/* private fields */);

Identifier of one supervised CLI execution.

Lives here with the other identifiers rather than with the cost ledger that first needed it: a run is a core domain object, and several parts of the Tower will key off it.

Implementations

impl RunId

pub fn generate() -> Self

Mints a new identifier.

pub fn as_str(&self) -> &str

Returns the identifier as a string slice.

pub fn minted_at(&self) -> Option<Timestamp>

When this identifier was minted, which is when its run began.

A ULID carries a millisecond timestamp in its leading bits, so a run’s own name says how old it is. That matters because a run’s Hangar outlives the process: retention needs a directory’s age, and asking the name is exact where asking the filesystem is a guess — a copy, a restore or a backup tool rewrites mtime, which would make old work look new or new work look expired.

None when the identifier was not minted by Self::generate — anything hand-made, or a directory somebody else left in a Hangar. Callers should read that as “do not touch” rather than “too old”.
