Enum TrySendError 

pub enum TrySendError<T> {
    Full(T),
    Closed(T),
}

Error returned by MessageSender::try_send.

Preserves tokio’s Full / Closed distinction so consumers can retry-on-full or exit-on-closed with a match arm.

Variants

Full(T)

Channel is full; the message was NOT sent. Caller may retry later once the AppHarness has drained.

Closed(T)

AppHarness receiver has been dropped; the message was NOT sent and will never succeed on retry.

Implementations

impl<T> TrySendError<T>

pub fn into_inner(self) -> T
