Crate meadow

meadow is an experimental robotics-focused publish/request middleware for embedded Linux. It is built with a high preference for catching errors at compile-time over runtime and a focus on developer ergonomics, and can natively operate on any serde-compatible data type.

It uses a star-shaped network topology, with a focus on ease-of-use and transparent design and operation. It is more similar to ZeroMQ than to higher-level frameworks like ROS/2, but uses a central coordination process similar to MOOS-IvP. Meadow currently supports the following messaging patterns over different transport protocols:

Protocol	Publish	Request	Subscribe	Encryption
TCP	X	X	X
UDP	X	X	X
QUIC	X	X	X	X
