Release Notes

rayon-rs/rayon

v1.6.0

Compare Source

• The minimum supported rustc is now 1.56.
• The new IndexedParallelIterator::fold_chunks and fold_chunks_with methods
  work like ParallelIterator::fold and fold_with with fixed-size chunks of
  items. This may be useful for predictable batching performance, without the
  allocation overhead of IndexedParallelIterator::chunks.
• New "broadcast" methods run a given function on all threads in the pool.
  These run at a sort of reduced priority after each thread has exhausted their
  local work queue, but before they attempt work-stealing from other threads.
  • The global broadcast function and ThreadPool::broadcast method will
    block until completion, returning a Vec of all return values.
  • The global spawn_broadcast function and methods on ThreadPool, Scope,
    and ScopeFifo will run detached, without blocking the current thread.
• Panicking methods now use #[track_caller] to report the caller's location.
• Fixed a truncated length in vec::Drain when given an empty range.

v1.5.3

Compare Source

• The new ParallelSliceMut::par_sort_by_cached_key is a stable sort that caches
  the keys for each item -- a parallel version of slice::sort_by_cached_key.

v1.5.2

Compare Source

• The new ParallelSlice::par_rchunks() and par_rchunks_exact() iterate
  slice chunks in reverse, aligned the against the end of the slice if the
  length is not a perfect multiple of the chunk size. The new
  ParallelSliceMut::par_rchunks_mut() and par_rchunks_exact_mut() are the
  same for mutable slices.
• The ParallelIterator::try_* methods now support std::ops::ControlFlow and
  std::task::Poll items, mirroring the unstable Try implementations in the
  standard library.
• The ParallelString pattern-based methods now support &[char] patterns,
  which match when any character in that slice is found in the string.
• A soft limit is now enforced on the number of threads allowed in a single
  thread pool, respecting internal bit limits that already existed. The current
  maximum is publicly available from the new function max_num_threads().
• Fixed several Stacked Borrow and provenance issues found by cargo miri.

v1.5.1

Compare Source

• The new in_place_scope and in_place_scope_fifo are variations of scope
  and scope_fifo, running the initial non-Send callback directly on the
  current thread, rather than moving execution to the thread pool.
• With Rust 1.51 or later, arrays now implement IntoParallelIterator.
• New implementations of FromParallelIterator make it possible to collect
  complicated nestings of items.
  • FromParallelIterator<(A, B)> for (FromA, FromB) works like unzip.
  • FromParallelIterator<Either<L, R>> for (A, B) works like partition_map.
• Type inference now works better with parallel Range and RangeInclusive.
• The implementation of FromParallelIterator and ParallelExtend for
  Vec<T> now uses MaybeUninit<T> internally to avoid creating any
  references to uninitialized data.
• ParallelBridge fixed a bug with threads missing available work.
