Kafka Rust Client
- This library is primarily documented through examples in its API documentation.
- Documentation about Kafka itself can be found at the its project home page.
This crate works with Cargo and is on crates.io. The API is currently under heavy movement although we do follow semantic versioning (but expect the version number to grow quickly.)
[dependencies] kafka = "0.2"
To build kafka-rust you'll need
libsnappy-dev on your local machine.
If that library is not installed in the usual path, you can export the
LD_RUN_PATH environment variables before
This is a higher-level Consumer API for Kafka. It provides convenient offset management support on behalf of a specified group. This is the API a client application of this library wants to use for receiving messages from Kafka.
This is a higher-level Producer API for Kafka. It provides convenient automatic partition assignment capabilities through partitioners. This is the API a client application of this library wants to use for sending messsages to Kafka.
is the central point of this API. However, this is a mid-level
abstraction for Kafka rather suitable for building higher-level APIs.

[Creating a topic] (https://kafka.apache.org/08/quickstart.html)
Note unless otherwise explicitely stated in the documentation, this library will ignore requests to topics which it doesn't know about. In particular it will not try to retrieve messages from non-existing/unknown topics. (This behavior is very likely to change in future version of this library.)
Given a local kafka server installation you can create topics if the
following command (
kafka-topics.sh is part of the Kafka
kafka-topics.sh --topic my-topic --create --zookeeper localhost:2181 --partition 1 --replication-factor 1
