Tokio v0.2.10

on GitHub

Introduces a task-local storage solution that works with Rust's "task" concept and supports multiplexing futures on the same runtime task (#2126). A number of other incremental improvements are included.

This release includes a few fixes, including fixing a scenario in which undefined behavior could be introduced when the user provided a buggy AsyncRead implementation.

Fixes

• #[tokio::main] when rt-core feature flag is not enabled (#2139).
• remove AsyncBufRead from BufStream impl block (#2108).
• potential undefined behavior when implementing AsyncRead incorrectly (#2030).

Added

• BufStream::with_capacity (#2125).
• impl From and Default for RwLock (#2089).
• io::ReadHalf::is_pair_of checks if provided WriteHalf is for the same
  underlying object (#1762, #2144).
• runtime::Handle::try_current() returns a handle to the current runtime (#2118).
• stream::empty() returns an immediately ready empty stream (#2092).
• stream::once(val) returns a stream that yields a single value: val (#2094).
• stream::pending() returns a stream that never becomes ready (#2092).
• StreamExt::chain() sequences a second stream after the first completes (#2093).
• StreamExt::collect() transform a stream into a collection (#2109).
• StreamExt::fuse ends the stream after the first None (#2085).
• StreamExt::merge combines two streams, yielding values as they become ready (#2091).
• Task-local storage (#2126).
