**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** The Json writer in https://github.com/apache/arrow-rs/blob/master/arrow/src/json/writer.rs will `panic!` if it hits unsupported data types **Describe the solution you'd like** It would be nice if the code instead returned `Result<()>` -- so that would mean: 1. Remove all `panic!` macros from `writer.rs` 2. Remove all `unwrap()` or `expect()` that are not in the test code from writer.rs 3. Get code to compile again The panic/unwrap would be replaced with something like: ```rust Err(ArrowError::JsonError(format!( "data type {:?} not supported", t ))), ``` With the appropriate error message Interestingly, the `Writer` itself seems to return`Result` but I think the two free public functions `array_to_json_array` and `record_batches_to_json_rows` would need to be updated to return `Result<>` https://docs.rs/arrow/6.5.0/arrow/json/writer/index.html#functions **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** As noted on https://github.com/apache/arrow-rs/pull/1149#discussion_r782430643 -- This is an automated message from the Apache Git Service.
