Macros§

join: The join macro makes it very easy to iterate over multiple components of the same Entity at once.

ComponentIterator: Iterates over components using a provided bitset. Each time the bitset has a 1 in index i, the iterator will fetch data from the storage at index i and return it as an Option.
ComponentIteratorMut: Iterates over components using a provided bitset. Each time the bitset has a 1 in index i, the iterator will fetch data from the storage at index i and return it as an Option.
Components: Holds components of a given type indexed by Entity. We do not check if the given entity is alive here, this should be done using Entities.
Entities: Holds a list of alive entities. It also holds a list of entities that were recently killed, which allows to remove components of deleted entities at the end of a game frame.
Entity: An entity index. They are created using the Entities struct. They are used as indices with Components structs.
EntityIterator: Iterator over entities using the provided bitset.

create_bitset: Creates a bitset big enough to contain the index of each entity. Mostly used to create caches.

BitSetVec: The type of bitsets used to track entities in component storages. Mostly used to create caches.
