❤️ First off, serde is amazing. :)
I'm using serde_yaml::to_writer()
to dump a struct to a yaml file. In the struct I have tmdb_genre: Vec<u64>
which outputs like this:
tmdb_genre:
- 35
- 10751
- 9648
- 10749
While this is correct yaml, for purely aesthetic reasons I would like it to look like this:
tmdb_genre: [35, 10751, 9648, 10749]
I tried adding #[serde(flatten)]
to the struct element but I get runtime Error("can only flatten structs and maps (got a sequence)"). Is there any way of doing this w/o resorting to post processing of the yaml (ie sed)? Thanks!

Did you found the solution?

Nope, doing a system call to sed afterwards. Thanks for asking. :)
