Trait Decode 

pub trait Decode {
    const ID: u64 = 0;

    // Required method
    fn decode(
        buf: Bytes,
        ctx: Option<&DecodeContext>,
    ) -> Result<Self, DecodeError>
       where Self: Sized;
}

Describes how to decode a remote message.

Provided Associated Constants

const ID: u64 = 0

Message identifier. A remote message should have an unique identifier so the Handler<RemoteMessage> can dispatch the message to the proper handler.

Here unique means that for one particular actor type, the messages that can be handled by it must have unique identifiers, but two different actor can have messages share the same identifier.

The identifier in Encode and Decode must be the same for the same message type.

The derived implementation of Handler<RemoteMessage> relies on this identifier to work properly. If you do not use the derived implementation of Handler<RemoteMessage>, you can ignore this requirement and just use the default value.

(u64::MAX - 255) ~ u64::MAX is reserved for internal use.

Required Methods

fn decode(buf: Bytes, ctx: Option<&DecodeContext>) -> Result<Self, DecodeError>

where Self: Sized,

Decodes the remote message from the provided buffer.

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.
