Module near_async::messaging

Structs

• LateBoundSender
  Sometimes we want to be able to pass in a sender that has not yet been fully constructed. LateBoundSender can act as a placeholder to pass CanSend and CanSendAsync capabilities through to the inner object. bind() should be called when the inner object is ready. All calls to send() and send_async() through this wrapper will block until bind() is called.
• MessageWithCallback
  Used to implement an async sender. An async sender is just a Sender whose message is MessageWithCallback<M, R>, which is a message plus a callback function (which resolves the future that send_async returns).
• Noop
• Sender
  Wraps a CanSend. This should be used to pass around an Arc<dyn CanSend>, instead of spelling out that type. Using a wrapper struct allows us to define more flexible APIs.

Enums

• AsyncSendError
  Generic failure for async send.

Traits

• CanSend
  Trait for sending a typed message.
• IntoMultiSender
  A trait for converting something that implements individual senders into a multi-sender.
• IntoSender
  Extension functions to wrap a CanSend as a Sender.
• MultiSenderFrom
• SendAsync
  Extension trait (not for anyone to implement), that allows a Sender<MessageWithCallback<M, R>> to be used to send a message and then getting a future of the response.

Functions

• noop
  Creates a no-op sender that does nothing with the message.
