v1.1.0

API Documentation

This patch introduces a faster scheduler algorithm, Stream::throttle, and
stabilizes task::yield_now. Additionally we're introducing several more stream
APIs, bringing us to almost complete parity with the standard library.

Furthermore our path submodule now returns more context in errors. So if
opening a file fails, async-std will tell you which file was failed to open,
making it easier to write and debug programs.

Examples

let start = Instant::now();

let mut s = stream::interval(Duration::from_millis(5))
    .throttle(Duration::from_millis(10))
    .take(3);

s.next().await;
assert!(start.elapsed().as_millis() >= 5);

s.next().await;
assert!(start.elapsed().as_millis() >= 15);

s.next().await;
assert!(start.elapsed().as_millis() >= 25);

Added

• Added Stream::throttle as "unstable".
• Added Stream::count as "unstable".
• Added Stream::max as "unstable".
• Added Stream::successors as "unstable".
• Added Stream::by_ref as "unstable".
• Added Stream::partition as "unstable".
• Added contextual errors to the path submodule.
• Added os::windows::symlink_dir as "unstable".
• Added os::windows::symlink_file as "unstable".
• Stabilized task::yield_now.

Fixes

• We now ignore seek errors when rolling back failed read calls on File.
• Fixed a bug where Stream::max_by_key was returning the wrong result.
• Fixed a bug where Stream::min_by_key was returning the wrong result.

Changed

• Applied various fixes to the tutorial.
• Fixed an issue with Clippy.
• Optimized an internal code generation macro, improving compilation speeds.
• Removed an Unpin bound from stream::Once.
• Removed various extra internal uses of pin_mut!.
• Simplified Stream::any and Stream::all's internals.
• The surf example is now enabled again.
• Tweaked some streams internals.
• Updated futures-timer to 2.0.0, improving compilation speed.
• Upgraded async-macros to 2.0.0.
• Stream::merge now uses randomized ordering to reduce overall latency.
• The scheduler is now more efficient by keeping a slot for the next task to
  run. This is similar to Go's scheduler, and Tokio's scheduler.
• Fixed the documentation of the channel types to link back to the channel
  function.
