Simplified par_bridge to only pull one item at a time from the iterator,
without batching. Threads that are waiting for iterator items will now block
appropriately rather than spinning CPU. (Thanks @njaard!)
Added protection against recursion in par_bridge, so iterators that also
invoke rayon will not cause mutex recursion deadlocks.
Release rayon-core 1.10.1 (2022-11-18)
Fixed a race condition with threads going to sleep while a broadcast starts.
Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)
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.
Contributors
Thanks to all of the contributors for this release!
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.
