Struct Host 

pub struct Host { /* private fields */ }

The engine, as a plugin can reach it.

Cheap to clone and usable from any thread, so a plugin keeps one in a worker and pushes at the app whenever it has something. Nothing here blocks on the tick thread: a call queues its payload and returns.

Implementations

impl Host

pub fn call_handler( &self, event: &str, key: &str, fallback: &str, args: Vec<ScriptValue>, ) -> bool

Call a handler in the app’s script.

event is the handler name, key the identifier it receives so one handler can serve several sources, and fallback a handler to try when the app defines no event (empty for none).

Returns false when the engine is no longer taking events, which is what a plugin’s worker thread sees while the app shuts down.

pub fn emit(&self, commands: Vec<ScriptCommand>) -> bool

Apply commands, as if a call had emitted them.

Returns false when the engine is no longer taking events.

pub fn log(&self, level: LogLevel, message: &str)

Write a line to the engine’s diagnostic output.
