[dependabot]

Bumps mongodb from 1.2.5 to 2.0.0.

Release notes

Sourced from mongodb's releases.

v2.0.0

Description

The MongoDB Rust driver team is pleased to announce the v2.0.0 release of the mongodb crate. This release is the culmination of several months of work, and it contains a number of new features, API improvements, and bug fixes. It is intended that this release will be very stable and that mongodb will not have another major release for quite a long time.

Note that the new minimum supported Rust version (MSRV) is now 1.48.0.

Highlighted changes

The following sections detail some of the more important breaking changes included in this release. For a full list of changes, see the Full Release Notes section below.

Update dependency on tokio to v1.x (RUST-633)

The async runtime crate tokio reached 1.0, and the driver's dependency on it was updated to 1.0 accordingly. This is a breaking change, since the driver will no longer work with earlier versions of tokio.

Update dependency on bson to v2.0.0 (RUST-1006)

The exported version of bson was updated to v2.0.0, which includes its own set of breaking changes. Check out the bson release notes for more information.

Transactions support (RUST-90)

This release adds driver support for transactions, which are supported on replica sets in MongoDB 4.0+ and on sharded clusters in MongoDB 4.2+. Transactions require the use of a ClientSession. Each operation in the transaction must pass the ClientSession into it via the _with_session suffixed version of the operation. For more information and detailed examples, see the ClientSession documentation.

use mongodb::options::{Acknowledgment, ReadConcern, TransactionOptions};
use mongodb::{
    bson::{doc, Document},
    options::WriteConcern,
};

let mut session = client.start_session(None).await?;
let txn_options = TransactionOptions::builder()
.write_concern(WriteConcern::builder().w(Acknowledgment::Majority).build())
.read_concern(ReadConcern::majority())
.build();
session.start_transaction(txn_options).await?;
collection
.insert_one_with_session(doc! { "x": 1 }, None, &mut session)
.await?;
collection
.delete_one_with_session(doc! { "x": 2 }, None, &mut session)
.await?;
session.commit_transaction().await?;

The "snapshot" read concern level was also introduced as part of this feature.
