Installation

By now, the only way of installing it is building it from source or via cargo install kafka-topic-analyzer. In both cases you need to have the rust toolchain installed via http://rustup.rs/.

Dependencies

librdkafka

When installed from source, the binary can build librdkafka as part of the dependency resolution process. Please see the rdkafka-rust dependency documentation for the detailed requirements.

The rdkafka-rust dependency exports a feature flag, which enables dynamic linking of the librdkafa dependency.

You can compile this project with cargo build --features "dynamic_linking" in order to use the shared library instead of building it with the dependencies.
