Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.34.0...async-nats/v0.35.0

Overview

This release introduces performance improvements (thanks to poll_recv_many #1189), improves resilience of ordered consumers by recreating them in more cases while having less server calls. It also adds some new features.

Breaking Changes

Breaking changes are minor, however, all are worth mentioning.

• Don't expose BoxFuture in public API by @oscarwcl in https://github.com/nats-io/nats.rs/pull/1167

This change simplifies lifetimes of Boxed Futures, by making them static. It should not affect most users, and if it does, removal of the lifetime should be a quick fix.

• Add check for max payload size when publishing messages by @Jarema in https://github.com/nats-io/nats.rs/pull/1211

The client was not checking if the message payload size was not exceeding the limits of the server it is connected to. While doing the fix, the error returned was changed into one consistent with others: a struct with enum of possible error variants under kind() method, of which one is MaxPayloadExceeded. This should not break users, as before there was no enum in the first place, but it is a breaking change.

• Add stream name check to all stream management methods by @Jarema in https://github.com/nats-io/nats.rs/pull/1214

It added new enum variant to Consumer and Stream error kinds. Breaking for those who match those errors in exhaustive manner.

• Remove clone in message split method by @AbstractiveNord in https://github.com/nats-io/nats.rs/pull/1172

This changes to be a mut self from self while removing unnecessary clone.

Full Changelog: https://github.com/nats-io/nats.rs/compare/nats/v0.24.1...async-nats/v0.34.0

Overview

This release introduces last planned breaking changes and stabilizes the async API.

Subject in publish methods

The biggest change is how subjects are handled. Until now, publish was of type String:

client.publish("subject".to_string(), "data".into()).await?;

This was easy to understand and reason about, but had two downsides:

1. It was always allocating
2. It was cumbersome for codebases working with &'static str

The signature has been change into:

// Signature
async fn publish(subject: impl ToSubject, payload: Bytes)
// Usage
client.publish("subject", "data".into()).await?;

This is not only more concise, but also allows avoiding allocations when subject is static, or when it is Subject type that can be cheaply cloned leveraging memory optimized bytes::Bytes mechanism under the hood.

Service API improvements

Beyond that, there were a lot of improvements to Service API to address cross-language compatibility issues. All structures are now tested against common cross-language json schemas. Thanks @jadamcrain for all the feedback, issues nad PRs related to Service API!

Docs improvements

Despite every method having documentation with examples, we were aware that sometimes its hard to navigate the docs to find what someone is looking for. This was addressed by adding module-level docs.

Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.32.0...async-nats/v0.33.0

Overview

Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.32.0...async-nats/v0.32.1

Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.30.1...async-nats/v0.32.0

This release focuses on improvements of heartbeats in JetStream Consumers.

Heartbeats are a tool that tells the user if the given consumer is healthy but does not get any messages or if the reason for no message is an actual problem. However, if the user was not polling the Stream future for the next messages for a long time (because it was slowly processing messages), that could trigger idle heartbeats, as the library could not see the heartbeat messages without messages being polled.

This release fixes it by starting the idle heartbeat timer only after Stream future is polled (which usually means calling messages.next().await).

Overview

This release focuses on preparing for the 1.0.0 release.

The main highlight is Core NATS concrete errors. There are also security improvements (@paolobarbolini thanks for your help!) and JetStream API improvements.

Concrete Errors

New errors returned by Core NATS methods are not boxed anymore. They themselves are not enums, but follow more flexible approach of std::io::Error and expose kind() method to get the enum. All enums implement PartialEq for more straightforward assertions.

Added

• Add support for stream subject transform by @n1ghtmare in https://github.com/nats-io/nats.rs/pull/867
• Add retaining server list order option by @Jarema in https://github.com/nats-io/nats.rs/pull/890

Fixed

• Fix a typo in the documentation by @marcusirgens in https://github.com/nats-io/nats.rs/pull/864
• Fix reconnect burst on auth failure by @Jarema in https://github.com/nats-io/nats.rs/pull/890

Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.28.0...async-nats/v0.29.0

Overview

This release prepares the client for 2.10.0 server release and adds some fixes and improvements.

To use the new features before the server 2.10.0 release, enable server_2_10 feature.

Breaking Changes

To enable NAK with backoff, AckKind::NAK enum variant was changed

What was before:

AckKind::Nak

now is:

AckKind::Nak(Option<std::time::Duration>)

Which means a standard NAK example

let message = messages.next().await?;
message.ack_kind(AckKind::Nak).await?;

Now should be used like this

let message = messages.next().await?;
message.ack_kind(AckKind::Nak(None)).await?;

or with custom NAK

message.ack_kind(AckKind::Nak(Some(std::time::Duration::from_secs(10))).await?;

Consumer info cluster field is now Option

This field is provided only in clustered mode, so it's now properly inline with that.

Consumer idle heartbeat error does not terminate iterator

This change does not require any action from the users who want to continue using client as they do now, but those who would like to try continuing working with consumer, even if it returned idle heartbeats, now they can.

Added

• Add support for consumers with multiple filters (feature server_2_10) by @Jarema in https://github.com/nats-io/nats.rs/pull/814
• Add metadata support (feature server_2_10) by @Jarema in https://github.com/nats-io/nats.rs/pull/837

Full Changelog: https://github.com/nats-io/nats.rs/compare/async-nats/v0.23.0...async-nats/v0.24.0

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 https://github.com/nats-io/nats.rs/pull/727

Fixed

• Fix object store watch to retrieve only new/changed values by @Jarema in https://github.com/nats-io/nats.rs/pull/720
• Fix stack overflow in object store by @Jarema in https://github.com/nats-io/nats.rs/pull/731

Added

• Add customizable JetStream publish by @Jarema in https://github.com/nats-io/nats.rs/pull/728 request by @andrenth
• Add object store list by @Jarema in https://github.com/nats-io/nats.rs/pull/721
• Add docs lint by @Jarema in https://github.com/nats-io/nats.rs/pull/725

Overview

A patch release, including early feedback to 0.22.0.

Breaking Changes

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

Changed

• Flush on publish ack await by @Jarema in https://github.com/nats-io/nats.rs/pull/708

Fixed

• Fix typo in retry_on_initial_connect by @Jarema in https://github.com/nats-io/nats.rs/pull/713

Added

• Setup cargo deny to check licenses by @corbinu in https://github.com/nats-io/nats.rs/pull/703

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 acknowledgment 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 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 acknowledgments by @Jarema in https://github.com/nats-io/nats.rs/pull/644
• Add retry on initial connect by @Jarema in https://github.com/nats-io/nats.rs/pull/662

// or use a shortcut
let messages = consumer.messages().await?;

// after changes
let messages = consumer.stream().messages().await?;
// or with options
let messages = consumer.stream().max_bytes_per_bytes(1024).messages().await?;
