Contract

• assert Option<Path<u32>> returns Some(Path(42)) on a route with a valid path parameter
• assert Option<Path<u32>> rejects with 400 Bad Request instead of None when the path parameter in the route fails deserialization
• assert Option<Path<u32>> evaluates to None only when the matched route definition contains zero path parameters
• assert Option<Json<T>> evaluates to None only when the Content-Type header is completely omitted
• assert Option<Json<T>> rejects with 400 Bad Request instead of None when Content-Type is application/json but body has malformed JSON syntax
• assert Option<Json<T>> rejects with 422 Unprocessable Entity instead of None when Content-Type is application/json but body has schema or field type mismatches
• assert Option<Json<T>> rejects with 422 Unprocessable Entity instead of None when Content-Type is application/json but required fields are missing
• assert Option<Json<T>> rejects with 415 Unsupported Media Type instead of None when Content-Type header is non-JSON like text/plain
• assert Option<Json<T>> returns Some(Json(T)) when valid JSON body and Content-Type are provided
• assert a 1-tuple Path<(u32,)> on a 2-parameter route rejects with 500 Internal Server Error for arity mismatch instead of silently extracting the first parameter
• assert a 2-tuple Path<(u32, u32)> on a 2-parameter route extracts both parameters and returns 200 OK
