Crate sim_lib_stream_asio 

Modeled Windows ASIO stream-host adapter (in-process simulation).

Modeled tier, no native I/O. This crate is a pure-Rust, in-process MODEL of an ASIO backend, not a binding to the Steinberg ASIO SDK. The workspace forbids unsafe and the crate carries no -sys/FFI dependency, so it performs no real ASIO driver I/O – it serves deterministic, fake driver enumeration. The modeled tier is flagged by the default-on model feature; a native provider would live behind a separate FFI binding outside this repo.

This crate keeps validation independent of the Steinberg ASIO SDK and local audio drivers. It models provider-reported ASIO drivers, exposes stream-host inventory and open plans, and bridges ASIO-style process callbacks into ProcessBlock so the same graph processor code can run under fake Linux CI, Windows ASIO, and other host adapters.

Native ASIO providers are intentionally optional. A downstream provider must target Windows, arrange SDK headers/import libraries outside this repository, and populate the stable model types from driver enumeration.

Structs

AsioBackend

ASIO host backend with provider-supplied deterministic driver data.

AsioBufferSwitchBridge

Drives a processor from an ASIO-style buffer switch callback.

AsioDriver

SIM-visible ASIO driver metadata.

AsioLib

Host-registered lib exporting the ASIO stream-host cards, built on the shared SurfacePackLib substrate.

AsioPort

Routable ASIO port owned by a driver.

AsioTiming

Timing metadata accepted by an ASIO buffer switch.

Functions

asio_backend_symbol

Returns the stream-host backend identifier for ASIO (stream/host:asio).

asio_clock_symbol

Returns the clock identifier reported by ASIO host streams (clock:asio).

asio_sdk_build_requirements

Lists the prerequisites a downstream provider must satisfy to build a native ASIO backend, none of which this validation-only crate supplies.

asio_transport_symbol

Returns the transport identifier carried by ASIO host streams (stream/transport:asio).

install_stream_asio_lib

Installs the AsioLib into cx exactly once, registering its ASIO stream-host surface cards.
