Struct WorldDelta 

pub struct WorldDelta { /* private fields */ }

The set of shared-World cells written over one accounting window — the changed-set mark_wake_dirty intersects each wake condition’s read row against.

Two granularities, because that is exactly what the row can express (brink_format::DirectEffects::reads is “global cells this row may read”):

• globals — per-cell, by global slot index (the Program::global_index numbering World::set_global takes), so a condition reading gate is unaffected by a write to mood.
• bookkeeping — one coarse bit covering visit counts, turn counts, the turn index, and RNG state. Effect rows model no read of these (see FlowSleep::reads_bookkeeping), so there is nothing finer to intersect against.

Implementations

impl WorldDelta

pub fn globals(&self) -> &BTreeSet<u32>

The global slot indices written over this window.

pub fn touched_bookkeeping(&self) -> bool

Whether any bookkeeping cell (visit count, turn count, turn index, RNG state) was written over this window.

pub fn is_empty(&self) -> bool

Nothing was written at all — no policy can need re-evaluation on this window’s account.
