Description

Functionality related to index storage and the DefaultList type.

Synopsis

Documentation

Key used to store list indices

Parse a string of comma-delimited integers to a list. Unparseable substrings are left out of the result.

Serialize a list of integers as a comma-delimited Text

A list which, when indexed on non-existant positions, returns a default value.

Safe indexing of a DefaultList - returns the default value if the given index is out of bounds.
