Release async-nats/v0.25.0

Overview

This release focuses on service module, which leverages NATS primitives to provide API for creating and running horizontaly scalable microservices.

let client = async_nats::connect(server.client_url()).await.unwrap();

let mut service = client
    .add_service(async_nats::service::Config {
        name: "serviceA".to_string(),
        version: "1.0.0".to_string(),
        endpoint: "service_a".to_string(),
        schema: None,
        description: None,
    })
    .await?;
    
   while let Some(request) = service.next().await {
       request.respond(Ok("data".into())).await.unwrap();
}

As this is an experimental beta feature, to enable it, please add experimental feature to Cargo.toml NATS import.

Relase async-nats/v0.23.0

Overview

This release focuses on fixes around Object Store and customized JetStream Publish.

It also introduces a breaking change, as not all publish() methods did return PublishError, using the generic async_nats::Error instead. This has been fixed.

Breaking changes

• Make publish error types consistent by @Jarema in #727

Fixed

• Fix object store watch to retrieve only new/changed values by @Jarema in #720
• Fix stack overflow in object store by @Jarema in #731

• Add docs lint by @Jarema in #725

Changed

• Use debug macro for logging instead of println by @c0d3x42 in #716

• Improve docs formatting and fix links by @Jarema in #723

New Contributors

Full Changelog: async-nats/v0.22.1...async-nats/v0.23.0

Release sync nats 0.23.1

Overview

This is a minor sync client release with fixes to Object Store API

Fixed

• Fix sync object store encoding by @Jarema in #700

Added

• Add digest to sync object store by @Jarema in #709

Full Changelog: nats/v0.23.0...nats/v0.23.1

Release async-nats/v0.22.1

Overview

A patch release, including early feedback to 0.22.0.

Breaking Changes

Unfortunately, the last release included a typo in retry_on_initial_release.
This patch fixes it.
We decided to make a regular patch release without yanking as we're a pre 1.0.0 version.
To avoid similar situations in the future, spellcheck lint will be added before the next release.

Changed

• Flush on publish ack await by @Jarema in #708

Fixed

• Fix typo in retry_on_initial_connect by @Jarema in #713

Added

• Setup cargo deny to check licenses by @corbinu in #703

Release async-nats v0.22.0

Overview

This release introduces a number of changes and two breaking changes:

JetStream publish

Used to return ack:

let ack = jetstream.publish().await.unwrap();

But while adding publish that does not wait for an acknowledgement before returning,
we realized that we can leverage IntoFuture, so the new api is:

// This publishes the message, but do not wait until ack is received.
let future_ack = jetstream.publish().await.unwrap();
// to receive the acknowledge, `await()` the returned value:
let ack = future_ack.await().unwrap();

Event logging

After adding the initial retry on connect option, Event::Reconnect didn't make much sense.
Hence it was renamed to Event::Connected, which describes the current state without implications about the previous one.
For consistency, Event::Disconnect was renamed to Event::Disconnected.

Breaking changes

• Defer publish acknowledgements by @Jarema in #644
• Improve event logging by @Jarema in #672

Added

• Add support for mirrors and sources in Key Value Store by @Jarema in #676

        if let async_nats::Event::Reconnect = event {
            println!("reconnected");
        }
	// or match for all events
	match event {
		async_nats::Event::Disconnect => println!("disconnected"),
		async_nats::Event::Reconnect => println!("reconnected"),
		async_nats::Event::ClientError(err) => println!("client error occured: {}", err);
	}
