Struct HostCallback 

pub struct HostCallback { /* private fields */ }

A reference to the host which allows the plugin to call back and access information.

Panics

All methods in this struct will panic if the plugin has not yet been initialized. In practice, this can only occur if the plugin queries the host for information when Default::default() is called.

struct ExamplePlugin;

impl Default for ExamplePlugin {
    fn default() -> ExamplePlugin {
        // Will panic, don't do this. If needed, you can query
        // the host during initialization via Vst::new()
        let host: HostCallback = Default::default();
        let version = host.vst_version();

        // ...
    }
}

Implementations

pub fn vst_version(&self) -> i32
