[erlang-questions] Best choice for complex data structure
Thu Jan 24 12:37:03 CET 2019
I'm trying to figure out how to shape the (musical) data. In everyday
language, a musical idea has an architecture of formal nested units and
gestures made up of one or more events which have sounds and silences.
In Rust, the latter part of the above would yield a statement like:
which is manageable. But when I think about accessing data nested many
levels deep in Erlang, I'm kinda flummoxed. Instinctively, I don't think
transliterating something like this to records (or even maps?) is the
way to go?
All suggestions greatly appreciated.
