Aeron client written in Rust

About aeron-rs

Aeron is efficient reliable UDP and IPC message transport. Originally it was developed by RealLogic and hosted on GitHub real-logic/aeron

Aeron has two main components:

  • Media driver
  • Client library

The client library is linked with applications and allows several applications to talk with each other through Media driver(s). For more information about how Aeron works please read documentation.

aeron-rs library implements client functionality to work with Aeron Media driver. To get functioning system one need to download (and compile) Media driver from real-logic/aeron and write some Aeron enabled application using aeron-rs. Examples of such applications could be found inside the bin and in the library integration tests.

Why Aeron?

Aeron could be a good choice if you need to organize fast and ordered message streams. There are number of widely used messaging frameworks and to choose the right one for your particular case it is better to test them if close to real-life situations and compare the performance. Just some hints why Aeron could be a good choice:

  • Supports various transmission media without the need to change application code when switching between the media. Application can use IPC (shared memory) today and could switch to UDP in a matter of config change and restart.
  • Can work over UDP which is generally faster than over TCP (as some other messaging systems do)
  • Provides reliable and ordered message flow (even over UPD). Not all fast messaging frameworks guaranty messages order but Aeron do

Running library tests

Integration tests for aeron-rs assume that Media driver executable (aeronmd) is present in the PATH. So prior to run these tests install aeronmd accordingly. Also integration tests designed to run sequentially one by one. Therefore use

cargo test -- --test-threads=1

command to run them.

Tips for contributors

If you use POSIX-compliant OS (or at least has /bin/sh), you can use predefined git pre-push hook to ensure coding standards are met.

ln -s ../../.pre-push.sh .git/hooks/pre-push

Also, if you use IDE from IntelliJ IDEA family with Rust plugin, you can enable autoformatting:

Settings -> Languages and Frameworks -> Rust -> Rustfmt -> Run rustfmt on Save
