|
|
//! Erlang-style green-thread actor concurrency for Rust.
|
|
//!
|
|
//! v0.1 is single-threaded. One scheduler, one OS thread. The scheduler
|
|
//! cooperatively interleaves green-thread actors with hand-rolled context
|
|
//! switches. Actors communicate by sending `Send` messages over channels;
|
|
//! every actor has a supervisor, which is itself just an actor with a
|
|
//! `Receiver<Signal>`.
|
|
//!
|
|
//! See `LOOM.md` for the design intent and the deferred-for-later list.
