Enum ractor::errors::MessagingErr

pub enum MessagingErr<T> {
    SendErr(T),
    ChannelClosed,
    InvalidActorType,
}

A messaging error has occurred

Variants

SendErr(T)

The channel you’re trying to send a message too has been dropped/closed. If you’re sending to an crate::ActorCell then that means the actor has died (failure or not).

Includes the message which failed to send so the caller can perform another operation with the message if they want to.

ChannelClosed

The channel you’re trying to receive from has had all the senders dropped and is therefore closed

InvalidActorType

Tried to send a message to an actor with an invalid actor type defined. This happens if you have an crate::ActorCell which has the type id of its handler and you try to use an alternate handler to send a message

Implementations

impl<T> MessagingErr<T>

pub fn map<F, U>(self, mapper: F) -> MessagingErr<U>

where F: FnOnce(T) -> U,

Map any message embedded within the error type. This is primarily useful for normalizing an error value if the message is not needed.

Trait Implementations
