Generally, you need to provide your own data structures and associated
algorithms. There is a btree library, but that's about it.

However, as GRASS is licensed under the GPL (version 2 or later), you
can use code from other GPL or GPL-compatible (LGPL, MIT, new BSD
licences) software.

The usual approach is to find a similar module and use that as a
template.
