I'm happy to announce the immediate availability of Siena 3, my data provider agnostic ORM for Rust. This release includes a number of bug fixes and improvements. Some of the changes are breaking changes.

YAML and FrontMatter data parsing improvements

YAML parsing has much improved. When previously YAML parsing only supported HashMap<String, String>, as in root level key-value only and nothing else, then now the YAML parser supports a variety of new data structures such as String, usize, bool, Vec<RecordData> and HashMap<String, RecordData> where RecordData is:

pub enum RecordData {
    Str(String),
    Num(usize),
    Bool(bool),
    Map(HashMap<String, RecordData>),
    Vec(Vec<RecordData>),
}

Meaning that yes, you can now have recursive data structures in YAML (and the YAML section in FrontMatter files).

Name changes

• when_isnt method is now when_is_not
• when_hasnt method is now when_has_not
• RecordSortOrder::Custom is now RecordSortOrder::CustomStr

usize custom sorting

I renamed the RecordSortOrder::Custom to CustomStr because I also introduced a new sorter called RecordSortOrder::CustomNum which sorts usize values in the same way the CustomStr sorts strings.

I dogfood Siena myself for this very website actually, in Vau, my in-progress static site generator, and the above improvements are a direct result of me wanting to use Siena for my own purposes and finding it lacking. Dogfooding is great!
