Crate truce_rack_core 

Host-side core for the rack audio-plugin framework.

truce-rack-core defines the contracts every format wrapper (truce-rack-clap, truce-rack-vst3, truce-rack-au, …) implements: the Plugin trait, the AudioBuffer / EventList / ProcessContext passed into process, the BusLayout that declares bus topology, and the FFI-edge catch_unwind helpers in wrapper.

No FFI lives here. The crate compiles on every platform with no system dependencies — a consumer that depends on truce-rack-core and on a single format wrapper picks up exactly that format’s transitive deps.

Mapping from truce

truce-rack-core mirrors truce-core on the host side. The names parallel deliberately:

truce (plugin)	rack (host)
PluginLogic	Plugin
PluginExport	PluginScanner
AudioBuffer	AudioBuffer
EventList	EventList
ProcessContext	ProcessContext
BusLayout	BusLayout
PluginInfo	PluginInfo
wrapper::run_*	wrapper::run_*

A host targeting one format depends on truce-rack-core plus that format’s wrapper crate; a multi-format host depends on truce-rack-core plus each wrapper it needs.
