sim-lib-server 0.1.0

//! SIM's server library: a loadable lib that serves eval and agents over a
//! transport. It exposes sites (local, coroutine, pipeline, loop, fabric),
//! frame routing, REPL drivers, connections, and transports so callers can
//! request evaluation, stream replies, and run agent loops across the runtime.
//!
//! Transports are in-process by default: the default feature set enables no
//! network surface. The network/HTTP transport is the non-default
//! `server-net-http` feature and must be opted into explicitly; the various
//! `trigger-*` features add their respective inbound triggers the same way.
