Enum GenericSenderVariants 

enum GenericSenderVariants<T: Serialize> {
    Ipc(IpcSender<T>),
    Crossbeam(Sender<Result<T, Error>>),
}

The actual GenericSender variant.

This enum is private, so that outside code can’t construct a GenericSender itself. This ensures that users can’t construct a crossbeam variant in multiprocess mode.

Variants

Ipc(IpcSender<T>)

Crossbeam(Sender<Result<T, Error>>)

A crossbeam-channel. To keep the API in sync with the Ipc variant when using a Router, which propagates the IPC error, the inner type is a Result. In the IPC case, the Router deserializes the message, which can fail, and sends the result to a crossbeam receiver. The crossbeam channel does not involve serializing, so we can’t have this error, but replicating the API allows us to have one channel type as the receiver after routing the receiver .
