Function leo_span::span_json::serialize

pub fn serialize<S: Serializer>(
    span: &Span,
    serializer: S,
) -> Result<S::Ok, S::Error>

The AST contains a few tuple-like enum variants that contain spans. #[derive(Serialize, Deserialize)] outputs these fields as anonymous mappings, which makes them difficult to remove from the JSON AST. This function provides a custom serialization that maps the keyword span to the span information.
