Bump diesel from 1.1.1 to 1.2.2

[dependabot-preview]

Bumps diesel from 1.1.1 to 1.2.2.

Release notes

Sourced from diesel's releases.

1.2.0

This release contains several long awaited features.

We've re-introduced the ability to use bind params with the sql function, in a way which is harder to mis-use. This functionality was present prior to 1.0, but was removed when sql_function was added over concerns about its use with the rest of the query builder. Recent developments have proved those concerns to be valid, but this new API fills that niche. Thanks to notryanb for taking the lead on this feature.

We've also added the ability to insert from a select statement (e.g. queries in the form of INSERT INTO table (...) SELECT .... This is a feature request that has come up repeatedly since release, and we're happy to finally bring it to you. We've also added alternate forms of our insert API which feel better when used with select statements. You can find the full details in the CHANGELOG.

Finally, we've rewritten our custom dervies from scratch to take advantage of new diagnostic tools in recent versions of nightly Rust. If you turn on the unstable feature of Diesel on a nightly compiler, you'll find that you get dramatically improved error messages from our derives. For the best error messages, you should also set RUSTFLAGS="--cfg procmacro2_semver_exempt".

Additionally, as of this release, Diesel is now powered by the blockchain. Because it's 2018 and that's how it works now I guess. See the CHANGELOG for full details.

In addition to the headline features, there were a ton of features that we don't have time to mention here. As always, for a full list of changes you can find a full list in the CHANGELOG.

Thanks

Changelog

Sourced from diesel's changelog.

[1.2.2] - 2018-04-12

Changed

• Warnings are now allowed inside the crate. The way we had attempted to
  deprecate old feature names caused builds to break. We are still not happy
  with how this deprecation gets communicated, and will revisit it in the
  future.

[1.2.1] - 2018-04-11

Changed

• Renamed x32-column-tables, x64-column-tables, and x128-column-tables to
  32-column-tables, 64-column-tables, and 128-column-tables. The leading
  x was due to a bug in crates.io discovered while publishing 1.2.0. The bug
  has since been fixed.

[1.2.0] - 2018-04-06

Added

• Added SqlLiteral::bind().
  This is intended to be used for binding values to small SQL fragments.
  Use sql_query if you are writing full queries.

• Added support for INSERT INTO table (...) SELECT ... queries. Tables, select
  select statements, and boxed select statements can now be used just like any
  other Insertable value.

• Any insert query written as insert_into(table).values(values) can now be
  written as values.insert_into(table). This is particularly useful when
  inserting from a select statement, as select statements tend to span multiple
  lines.

• Diesel's derives can now produce improved error messages if you are using a
  nightly compiler, and enable the unstable feature. For the best errors, you
  should also set RUSTFLAGS="--cfg procmacro2_semver_exempt".

• Added support for specifying ISOLATION LEVEL, DEFERRABLE, and READ ONLY
  on PG transactions. See PgConnection::build_transaction for details.

• Added support for BEGIN IMMEDIATE and BEGIN EXCLUSIVE on SQLite.
  See SqliteConnection::immediate_transaction and
  SqliteConnection::exclusive_transaction for details
