Description

I cannot seem to find the enum's default attribute as documented in the spec

I'm trying to create an avdl parser and this is a blocker for me. I was wondering if there's a reason for this. Otherwise I can submit a PR, please let me know, thanks.

Code sample:

let schema_str = r#"{"name":"Shapes","type":"enum","symbols":["SQUARE","TRIANGLE","CIRCLE","OVAL"], "default": "SQUARE"}"#;
let r = Schema::parse_str(schema_str).unwrap();
let can = r.canonical_form();
println!("{r:?}");
println!("{can}");

Observe the enum in its canonical form is missing the default.

Looking at the Enum's code, we cannot see a default field:

I apologize if this is somehow wrong
