Struct kpal_plugin::PluginData

#[repr(C)]
pub struct PluginData { /* fields omitted */ }

An opaque struct that contains the state of an individual plugin.

The daemon does not actually work directly with structs provided by a plugin library. Instead, they are hidden behind pointers to opaque structs of this type. The kpal-plugin FFI code takes care of casting the pointers back into the appropriate type inside the library code.

Notes

In Rust, an opaque struct is defined as a struct with a field that is a zero-length array of unsigned 8-bit integers. It is used to hide the plugin's state, forcing all interactions with the data through the functions in the vtable instead.
