Required Methods

fn on_method_call<'life0, 'async_trait>( &'life0 self, call: MethodCall, ) -> Pin<Box<dyn Future<Output = PlatformResult> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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 call before any other methods.

Note: You can use crate::util::Late to store the weak reference.

fn assign_invoker(&self, _invoker: AsyncMethodInvoker)

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

Note: You can use crate::util::Late to store the invoker.

fn on_isolate_destroyed(&self, _engine: IsolateId)

Called when engine is about to be destroyed.

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

Registers itself 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.
