Updates diesel-async from 0.7.4 to 0.9.0

Release notes

Sourced from diesel-async's releases.

Diesel-Async 0.9.0

Changes

• Change all transaction related functions to accept an real async closure instead of the scoped boxed variant. This change requires adujsting all call sides of transaction based functions from conn.transaction(|conn| async move {/* your code */}.scoped_boxed()) to conn.transaction(async |conn| /* your code */)

Fixed

• Fixed an unsound access to padding values while deserializing Date/Time values in the mysql backend Thanks to @​paolobarbolini for finding this issue.

You can support the development of Diesel by:

• Contributing Code, Documentation or Guides. Checkout the planing for Diesel 2.4 for open tasks.
• Providing knowledge and help to maintain the MySQL/MariaDB backend. This is currently the only in-tree backend that is not used by any maintainers, so having someone around that actually uses this backend would be very helpful for the Diesel project.
• Answering questions in our discussion forum
• Reporting bugs in our issue tracker
• Helping triaging issues in our issue tracker
• Sponsoring the maintainers.
