Trait MethodHandler 

pub trait MethodHandler: Sized + 'static {
    // Required method
    fn on_method_call(&self, call: MethodCall, reply: MethodCallReply);

    // Provided methods
    fn assign_weak_self(&self, _weak_self: Weak<Self>) { ... }
    fn assign_invoker(&self, _invoker: MethodInvoker) { ... }
    fn on_isolate_destroyed(&self, _isolate: IsolateId) { ... }
    fn register(self, channel: &str) -> RegisteredMethodHandler<Self> { ... }
}

Required Methods

fn on_method_call(&self, call: MethodCall, reply: MethodCallReply)

Provided Methods

fn assign_weak_self(&self, _weak_self: Weak<Self>)

Implementation can store weak reference if it needs to pass it around. Guaranteed to be called before any other methods.

fn assign_invoker(&self, _invoker: MethodInvoker)

Keep the method invoker if you want to call methods on engines.

fn on_isolate_destroyed(&self, _isolate: IsolateId)

Called when isolate is about to be destroyed.

fn register(self, channel: &str) -> RegisteredMethodHandler<Self>

Register self for handling platform channel methods.

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.
