Description

The MongoDB Rust driver team is pleased to announce the first beta of the driver, v0.10.0.

Major Features

Async API

The Rust driver now provides an async API which can be used with either tokio or async-std. By default, the driver uses tokio primitives for things like TcpStreams, although the runtime still must be started before calling into the driver API. To use async-std instead of tokio, specify the following in your Cargo.toml:

[dependencies.mongodb]
version = "0.10.0"
default-features = false
features = ["async-std-runtime"]

Sync API

The sync API from previous versions of the driver has been moved to the sync module and gated under the sync feature. To enable it, specify the following in your Cargo.toml:

[dependencies.mongodb]
version = "0.10.0"
default-features = false
features = ["sync"]

The sync API wraps the async API and blocks on the results of the async API method calls. It uses async-std under the hood.
