Trait Handler 

pub trait Handler<State: Clone + Send + Sync + 'static, Sig>:
    Send
    + Sync
    + 'static {
    // Required methods
    fn declaration(export_name: &str) -> String;
    fn inject(
        self,
        engine: &mut Engine<State>,
        export_name: &str,
    ) -> Result<(), EngineError>;

    // Provided method
    fn declaration_for(&self, export_name: &str) -> String { ... }
}

Required Methods

fn declaration(export_name: &str) -> String

fn inject( self, engine: &mut Engine<State>, export_name: &str, ) -> Result<(), EngineError>

Provided Methods

fn declaration_for(&self, export_name: &str) -> String

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
