Struct btrun::Envelope

source ·
pub struct Envelope<T: CallMsg> { /* private fields */ }
Expand description

Wraps a message to indicate if it was sent with call or send.

If the message was sent with call, then this enum will contain a channel that can be used to reply to it.

Implementations§

source§

impl<T: CallMsg> Envelope<T>

source

pub fn new(msg: T, reply: Option<Sender<T::Reply>>, from: ActorName) -> Self

source

pub fn from(&self) -> &ActorName

Returns the name of the actor which sent this message.

source

pub fn msg(&self) -> &T

Returns a reference to the message in this envelope.

source

pub fn reply(&mut self, reply: T::Reply) -> Result<()>

Sends a reply to this message.

If this message is not expecting a reply, or if this message has already been replied to, then an error is returned.

source

pub fn needs_reply(&self) -> bool

Returns true if this message expects a reply and it has not already been replied to.

source

pub fn split(self) -> (T, Option<Sender<T::Reply>>, ActorName)
