Module span_json

Provides custom serialize/deserialize implementations for Span.

Structs

• SpanMapVisitor 🔒
  This visitor is used by the deserializer to unwrap mappings and extract span information.

Functions

• deserialize
  Custom deserialization to enable removing spans from enums.
• serialize
  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.
