Releases: async-rs/async-std
v0.99.9
This patch upgrades our futures-rs
version, allowing us to build on the 1.39
beta. Additionally we've introduced map
and for_each
to Stream
. And we've
added about a dozen new FromStream
implementations for std
types, bringing
us up to par with std's FromIterator
implementations.
And finally we've added a new "unstable" task::blocking
function which can be
used to convert blocking code into async code using a threadpool. We've been
using this internally for a while now to async-std to power our fs
and
net::SocketAddr
implementations. With this patch userland code now finally has
access to this too.
Example
Create a stream of tuples, and collect into a hashmap
let a = stream::once(1u8);
let b = stream::once(0u8);
let s = a.zip(b);
let map: HashMap<u8, u8> = s.collect().await;
assert_eq!(map.get(&1), Some(&0u8));
Spawn a blocking task on a dedicated threadpool
task::blocking(async {
println!("long-running task here");
}).await;
Added
- Added
stream::Stream::map
- Added
stream::Stream::for_each
- Added
stream::Stream::try_for_each
- Added
task::blocking
as "unstable" - Added
FromStream
for allstd::{option, collections, result, string, sync}
types. - Added the
path
submodule as "unstable".
Changed
- Updated
futures-preview
to0.3.0-alpha.19
, allowing us to build onrustc 1.39.0-beta
. - As a consequence of this upgrade, all of our concrete stream implementations
now make use ofStream::size_hint
to optimize internal allocations. - We now use GitHub Actions through actions-rs,
in addition to Travis CI. We intend to fully switch in the near future. - Fixed a bug introduced in 0.99.6 where Unix Domain Listeners would sometimes become unresponsive.
- Updated our
sync::Barrier
docs to match std. - Updated our
stream::FromStream
docs to match std'sFromIterator
.
v0.99.8
This release came slightly ahead of schedule in order to fix compatibility issues with the newly released futures-preview@0.3.0-alpha.19
and Rust 1.39 beta release. Additionally we've introduced documentation for futures concurrency, and several new io::Read
methods!
Added
- Added README to examples directory.
- Added concurrency documentation to the futures submodule.
- Added
io::Read::take
method. - Added
io::Read::by_ref
method. - Added
io::Read::chain
method.
Changed
- Pin futures-preview to
0.3.0-alpha.18
, to avoid rustc upgrade problems. - Simplified extension traits using a macro.
- Use the
broadcast
module withstd::sync::Mutex
, reducing dependencies.
v0.99.7
This release includes 16 new APIs, including new streams combinators, Futures concurrency macros, and extensions to the sync and io submodules.
example using future::join
use async_std::future;
let a = future::ready(1);
let b = future::ready(2);
let c = future::ready(3);
let f = future::join!(a, b, c);
assert_eq!(f.await, (1, 2, 3));

v0.99.6
This release adds several new combinators, a work-stealing executor, and the ability to collect
streams using IntoStream
and FromStream
.
Additionally async-attributes 1.0
has been released which adds support for async fn main
, #[test] async fn
, and #[bench] async fn
.
Example
let a = stream::once(1u8);
let b = stream::once(2u8);
let c = stream::once(3u8);
let s = stream::join!(a, b, c);
assert_eq!(s.collect().await, vec![1u8, 2u8, 3u8]));
