Overview

A single-threaded execution context which owns a single thread. It's fully concurrent with limited parallelism.

Concurrency is restricted to a single thread. Fibers in the same context will never run in parallel to each other but they may still run in parallel to fibers running in other contexts (i.e. in another thread).

Fibers can use simpler and faster synchronization primitives between themselves (no atomics, no thread safety). Communication with fibers in other contexts requires thread-safe primitives.

A blocking fiber blocks the entire thread and all other fibers in the context.
