I think this highlights that while there are easy solutions to the problem the OP faced, they're difficult for a newcomer to discover. (I have been using Rust for a couple of months and I'd also have reached for serde and maybe serde_derive to solve the problem).
Hopefully this is something the Libz Blitz[0] will solve with their Rust Cookbook[1]. (You could almost but not quite arrive at as simple a solution from chapters 1 and 2).
