The Swim Rust SDK contains software framework for building stateful applications that can be interacted with via multiplexed streaming APIs. It is built on top of the Tokio asynchronous runtime and a Tokio runtime is required for any Swim application. Each application consists of some number of stateful agents, each of which runs as a separate Tokio task and can be individually addressed by a URI. An agent may have both public and private state which can either be held solely in memory or, optionally, in persistent storage. The public state of the agent consists of a number of lanes, analogous to a field in a record. There are multiple kinds of lanes that, for example, lanes containing single values and those containing a map of key-value pairs. The state of any lane can be observed by establishing a link to it (either from another agent instance or a dedicated client). A established link will push all updates to the state of that lane to the subscriber and will also allow the subscriber to request changes to the state (for lane kinds that support this). Links operate over a web-socket connection and are multiplexed, meaning that links to multiple lanes on the same host can share a single web-socket connection. There's a number of example applications available here: https://github.com/swimos/swim-rust/tree/main/example_apps https://github.com/swimos/swim-rust/tree/main/example_apps If you're interested in getting started with it a developer guide is available here https://www.swimos.org/server/rust/developer-guide/ https://www.swimos.org/server/rust/developer-guide/ as well as reference documentation here https://www.swimos.org/server/rust/ https://www.swimos.org/server/rust/ Previously on HN: - SwimOS: Distributed platform for building stateful, real-time streaming apps https://news.ycombinator.com/item?id=22920764 https://news.ycombinator.com/item?id=22920764 - Real-time traffic light status in Palo Alto powered by swim.ai https://news.ycombinator.com/item?id=19234286 https://news.ycombinator.com/item?id=19234286
