Modules

• std/ecs/column
• std/ecs/entityThe handle components are attached to, and the allocator that hands handles out.
• std/ecs/eventsEvents between systems: a buffer that survives a frame boundary, and the cursor a consumer reads it with.
• std/ecs/hierarchy
• std/ecs/query
• std/ecs/store

Everything

• type ColumnOne component type's dense column: the values in insertion order, the entity each row belongs to, and the row each entity occupies.
• type ComponentKeyThe name a scene file, an inspector and a schedule know a component type by.
• fn depthOrderentities in an order where every parent comes before its children, each one listed once.
• type EntitiesThe allocator of [Entity] handles, and the only place where a generation changes.
• type EntityWhat components are attached to: an index into the columns and the generation of the handle.
• type EventCursorWhere a consumer of Events has read up to.
• type EventsEvents as a value in a field of a group of columns: two buffers and a read cursor per consumer, exactly Bevy's shape.
• fn pairsEvery entity that has a First in first and a Second in second, in the order of the first column; an entity missing from the second drops out.
• type ParentWhose space an entity's transform is written in.
• fn quadruplesEvery entity that has a First, a Second, a Third and a Fourth, in the order of the first column.
• fn queryEvery entity that has a Component in space, with the value, in the order of the column.
• trait StoreWhat a package asks of a world: a column of one component type the package owns.
• fn triplesEvery entity that has a First, a Second and a Third, in the order of the first column.
