concurrency

Detailed Description

Headers under stlab/concurrency/ .

Abstractions for multi-core algorithms with less contention: futures, channels, serial queues, and related utilities. Tasks, executors, timers, and process lifecycle APIs belong to the public dependency stlab-execution, using their original header paths.

stlab::future differs from std::future in several ways:

• Continuations (then, recover) and combinators (when_all, when_any).
• Multiple continuations from the same future when the value type is copyable.
• Cancellation of uniquely contributing work when a future or packaged_task is destroyed before completion.
• Custom executors and automatic flattening of future<future<T>> to future<T>.

Executor/backend contracts are documented by stlab-execution's own local Doxygen build, not this package. That package and its documentation site are unpublished.

Tooling: building tests uses CMake and doctest. Contributors include Sean Parent, Foster Brereton, Felix Petriconi, and others.
