Struct RungTable 

pub struct RungTable {
    pub rungs: Vec<RungOccupancy>,
}

The typed, serializable snapshot of a whole ladder’s occupancy.

This is the shape the design mandates for rung state: Scope::Scheduler data, not attribute-string hacks. atune derives it from the StudyView on demand (AshaPruner::rung_table) rather than maintaining it as a mutable side-table, but the type exists so a caller can persist or ship it — it round-trips through a StateBlob unchanged.

Fields

rungs: Vec<RungOccupancy>

One entry per gating rung, ascending by resource.

Implementations

impl RungTable

pub fn build( view: &StudyView, ladder: &RungLadder, obj: usize, in_bracket: impl Fn(TrialNumber) -> bool, ) -> Self

Derives the whole ladder’s occupancy from the study snapshot.

in_bracket scopes it to one Hyperband bracket (pass |_| true for a plain ladder). Purely a read of the typed history — the same recovery the live promotion path does per rung, assembled across every rung for observability, testing and (optional) persistence.
