Bump diesel from 1.4.1 to 1.4.2

[dependabot-preview]

Bumps diesel from 1.4.1 to 1.4.2.

Release notes

Sourced from diesel's releases.

v0.99.0 (It's basically 1.0 except it's not)

This release is by far the largest Diesel has ever had. It serves 2 purposes. You can consider this release to be a beta for 1.0. However, 1.0 will have an important significant difference. Anything that is deprecated as of this release will not be present in the 1.0 release. This includes functions which were newly deprecated in 0.99. We know this may introduce a migration burden for some people, so we will continue to support the 0.99 line with bug fixes as long as there is demand and it is reasonable to do so.

Headline Features

This release is mainly focused on ergonomics. Our main new feature is the sql_query function. This is a new API which behaves similarly to sql, but it is entirely focused on cases where you want to write the entire query yourself. The main difference from sql is that you do not need to specify the return type of the query, and values are fetched by name rather than by index. This feature is still early, and there's a lot of features still to come (specifically evolving #[derive(QueryableByName)], but we think this feature will ease a lot of pains for cases where Diesel doesn't quite do what you need.

Additionally, you can now use tuples for inserts the same as you can for updates. If you've ever wanted to insert a row with just 1 or 2 values, and been annoyed that you needed a struct that you're only using in this one place, this feature will make you happy. We'll have new guides highlighting this feature soon.

Additionally, this release comes with a ton of quality of life features. Many of these changes are focused around making it easier to introduce line breaks naturally in your code. For example, .filter is now implemented on UpdateStatement, meaning you can write update(foo).filter(bar) instead of update(foo.filter(bar)). We've also introduced new APIs for insert and PG upsert which will have similar readability improvements.

Breaking Changes

This release includes more deprecations than any release prior. In particular, insert has been deprecated, along with our entire PG upsert API. All deprecations in this release have direct replacements, which will lead to code which formats much more nicely. It should be a mostly mechanical replacement for most apps. See the CHANGELOG file for details.

Growing the Team

With this release, we'd like to welcome several new members to the Diesel committer team. @​weiznich, @​notryanb, and @​katrinabrock you've all done excellent work and we're very excited to officially welcome you to the team!

Additional Thanks

In addition to the Diesel core and committer teams, 10 people contributed to this release. A huge thank you to:

• Adam Perry
• Alex Kitchens
• Alexey Zabelin
• Arnar Mar Sig
• Bob

Our only remaining blockers from this release and 1.0 are documentation changes, and having this tested in the wild. Thank you to every one of our users for your support, and we look forward to Diesel 1.0 by the end of the year!

Changelog

Sourced from diesel's changelog.

[1.4.2] - 2019-03-19

Fixed

• Parenthesis are now inserted around all mathematical operations. This means
  that (2.into_sql() + 3) * 4 will correctly evaluate to 20 as expected.
  Previously we would generate SQL that evaluated to 14. This could even result
  in runtime errors if multiple types were involved (for example, interval * (integer + 1))
