This package provides ordinary random access list, RAList, and also a length indexed variant, RAVec.

The data structure allows fast cons-operation (like ordinary list) but also fast random access (like non-functional arrays).

For lens or optics support see ral-lens and ral-optics packages respectively.

Similar packages

These packages don't provide length-indexed variants, and their RAList has opaque structure.
