Crate truce_rack_standalone 

cpal-driven standalone host for truce-rack.

Loads a single plugin via the appropriate format wrapper, opens the default cpal output device, and renders the plugin into the device’s audio stream. Optionally also opens a baseview window and embeds the plugin’s editor — see the gui feature and the windowed module.

Layout

• run_clap / run_vst3 / run_au / run_lv2 — one entry point per format wrapper. Each is feature-gated.
• run_with_plugin — common cpal plumbing every headless entry point uses.
• list_plugins — scan every enabled format and print one line per discovered plugin (powers --list).

Modules

cli

Shared command-line entry point for the standalone runner.

device

Audio output device + channel-routing selection for the standalone runner.

midi

Hardware MIDI input via midir.

midi_queue

Cross-thread MIDI queue.

transport

Host-side transport clock for the standalone runner.

Enums

Format

Which format the CLI picked. Used by the dispatcher so a single --name "Foo" flag can resolve against the right scanner.

PluginSelector

How the CLI identified the plugin it wants to load. Id is an exact unique-id match (CLAP plugin id, VST3 CID hex, AU 4cc triplet). Name is a case-insensitive substring against the plugin’s display name.

RunMode

What the standalone runner wants to do once it has a stream open: stay alive for seconds, or block until a user sends SIGINT.

Constants

GUI_AVAILABLE

Whether this build can open a plugin editor window — i.e. the gui feature is compiled in. false on Linux (baseview’s Linux backend is gated off) and on any --no-default-features build. Callers use it to decide whether --gui can be the default.

Functions

list_plugins

Scan every format compiled into this build and return a flat list of (format, info) pairs. Used by --list and by the screenshot bin’s per-plugin walk.

run_clap

Open a CLAP plugin by id or name and run it.

run_with_plugin

Open the default cpal output device and pump plugin into it, running for mode.
