The type of configurations for irmin-pack's indexing strategy, which dictates whether or not newly-appended pack entries should also be added to the index. Strategies are parameterised over:

• the length of the binary encoding of the object inside the pack entry (i.e. not accounting for the encoded hash and kind character);
• the kind of the pack object having been added.

Indexing more than the minimal strategy only impacts performance and not correctness: more indexing results in a larger index and a smaller pack file.

The strategy that indexes all objects.

The strategy that indexes as few objects as possible while still maintaing store integrity.

The strategy that is similar to the minimal strategy but it also indexes contents objects.

default is the indexing strategy used by irmin-pack instances that do not explicitly set an indexing strategy in Irmin_pack.config. Currently set to always.

is_minimal t is true if t is minimal.
