Module abi 

The raw C ABI shared between the generic interpreter and its plugins.

Everything in this module is #[repr(C)] and mirrored in the generated include/generic.h for non-Rust plugins. Plugin authors normally use the safe wrapper in the crate root instead of these types directly.

Structs

ClassDesc

Description of a plugin-defined class; one entry per class in ModuleDesc::classes.

FfiReturn

Result of a plugin function or a re-entering host callback.

FfiStr

A borrowed UTF-8 string. Not NUL-terminated.

FunctionDesc

Description of one exported plugin function.

GenericValue

An opaque generic runtime value.

HostApi

The host vtable handed to every plugin call.

MethodDesc

Description of one method of a plugin-defined class.

ModuleDesc

Description of a plugin module; returned by generic_plugin_init, the one symbol every plugin must export:

ValueDesc

Description of one exported plugin module value (a module constant, built once at import time).

Enums

FfiStatus

Discriminator for FfiReturn::status.

Constants

GENERIC_PLUGIN_ABI_VERSION

Version of the plugin ABI described by this crate.

Type Aliases

PluginFn

The signature every exported plugin function has.

PluginMethodFn

PluginTraverseFn

Per-class GC traversal callback, declared on ClassDesc::traverse.

PluginValueFn

The signature of a plugin value creator.

PluginVisitFn

Reports a held GenericValue to the host’s mark phase during GC.
