Trait OptionHandle 

pub trait OptionHandle<T>
where
    T: Clone + Send + Sync + 'static,
{
    // Required methods
    async fn is_some(&self) -> bool;
    async fn is_none(&self) -> bool;
}

An implementation of the ActorOption extension trait for the standard Option. This extension trait is made available on the Handle through the actify macro as OptionHandle. Within the actor these methods are invoked, which in turn just extend the functionality provided by the std library.

Required Methods

async fn is_some(&self) -> bool

Returns true if the option is a Some value.

Examples

let handle = Handle::new(Some(1));
assert!(handle.is_some().await);

async fn is_none(&self) -> bool

Returns true if the option is a None value.

Examples

let handle = Handle::new(Option::<i32>::None);
assert!(handle.is_none().await);

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.
