ActyxOS SDK
ActyxOS makes it easy to run distributed applications on multiple nodes. It is a piece of software that allows you to run your own apps on one or more edge devices and have these apps seamlessly communicate and share data with each other.
This crate defines the data types needed for communicating with ActyxOS and provides Rust bindings for the ActyxOS APIs.
Examples
Below you find a full example using the EventService
client that retrieves some events. Please adapt the semantics
to match your stored events
in order to see output.
Note: (this example needs the
client
feature to compile)
use actyxos_sdk::event_service::{EventService,
EventServiceError, Order, Subscription};
use futures::stream::StreamExt;
#[tokio::main]
pub async fn main() -> Result<(), EventServiceError> {
// client for locally running ActyxOS Event Service
let service = EventService::default();
// retrieve largest currently known event stream cursor
let offsets = service.get_offsets().await?;
// all events matching the given subscription
// sorted backwards, i.e. youngest to oldest
let sub = vec![Subscription::semantics("MyFish")];
let mut events = service
.query_upto(offsets, sub, Order::LamportReverse)
.await?;
// print out the payload of each event
// (cf. Payload::extract for more options)
while let Some(event) = events.next().await {
println!("{}", event.payload.json_value());
}
Ok(())
}

for serde
. The following features can be enabled in addition:
