Picodata development team is pleased to announce the availability of the new Tarantool Rust SDK 2.0 version.
Tarantool Rust SDK is an important auxiliary software used to develop third-party Tarantool modules in the Rust programming language. We develop and maintain the API and optimize its usage in certain scenarios.
The new release is a major upgrade that breaks compatibility with older versions, particularly in the following regards:
transaction::start_transactionhas a more flexible error handling, and is renamed totransaction::transaction- fiber::clock now returns a new tarantool::time::Instant type, which completely replaces std::time::Instant. Operations on it round the value by default, rather than causing panic.
- The tlua::LuaRead trait methods now return a WrongType error, which contains information about expected and received value types.
- Error::Decode now contains information about the expected data type and the received msgpack value content.
New features in this release:
- The #[tarantool::test] macro attribute and the test::test_cases function (available with the –features=test option), which can be used to write a test framework, for example as done in Tarantool-test.
- The proc::all_procs function, which returns an array of stored procedure descriptions,
specified using #tarantool::proc. This can be used to automate the declaration of stored procedures. - tarantool::network::client, an alternative async implementation of the IPROTO client based on our experimental async runtime.
- fiber::defer will now work more efficiently on newer versions of Tarantool (starting with 2.11).

Tarantool is a DBMS and computing platform that runs resident in RAM. This is a fast, reliable and highly scalable basis for building distributed systems with the business logic that the client needs. The Picodata software uses a revised and improved version of Tarantool to create storage clusters and run data processing applications written in Rust.
