# Description Makes the `from json --objects` command produce a stream, and read lazily from an input stream to produce its output. Also added a helper, `PipelineData::get_type()`, to make it easier to construct a wrong type error message when matching on `PipelineData`. I expect checking `PipelineData` for either a string value or an `Unknown` or `String` typed `ByteStream` will be very, very common. I would have liked to have a helper that just returns a readable stream from either, but that would either be a bespoke enum or a `Box<dyn BufRead>`, which feels like it wouldn't be so great for performance. So instead, taking the approach I did here is probably better - having a function that accepts the `impl BufRead` and matching to use it. # User-Facing Changes - `from json --objects` no longer collects its input, and can be used for large datasets or streams that produce values over time. # Tests + Formatting All passing. # After Submitting - [ ] release notes --------- Co-authored-by: Ian Manske <ian.manske@pm.me> |
