Enum Outcome 

#[non_exhaustive]
pub enum Outcome<T> {
    Unicast(T),
    GentleUnicast(T),
    Multicast(Vec<T>),
    GentleMulticast(Vec<T>),
    Broadcast,
    Discard,
    Default,
}

Specifies which actors will get a message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unicast(T)

Routes a message to an actor with the specified key. If there is no active or restarting actor for this key, it will be started.

GentleUnicast(T)

Routes a message to an actor with the specified key. If there is no active or restarting actor for this key, the message will be discarded, no actors are started.

Multicast(Vec<T>)

Routes a message to all actors with specified keys. If there is no active or restarting actors for these keys, they will be started.

GentleMulticast(Vec<T>)

Routes a message to all actors with specified keys. If there is no active or restarting actors for these keys, the message will be descarded, no actors are started.

Broadcast

Routes a message to all active actors.

Discard

Discards a message. If a message is discarded by everyone, the sending side gets an error.

Default

Acts as Broadcast for system messages and Discard otherwise.
