Enum Dispatched 

#[non_exhaustive]
pub enum Dispatched {
    Completed {
        remote_ref: Option<String>,
    },
    Retryable {
        code: String,
    },
    Permanent {
        code: String,
    },
    Unknown {
        remote_ref: Option<String>,
    },
}

How one send ended, as the sender classifies it.

There is no Result around it on purpose. Every failure mode of an external call has to land in exactly one of these four, and an author who returns an error instead of choosing has not answered the only question that matters: may this be sent again?

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Completed

The remote system accepted it, and said so.

Fields

remote_ref: Option<String>

Reference the remote gave, when it gave one.

Retryable

It did not arrive, and sending it again is safe.

Fields

code: String

Stable code, never free text.

Permanent

The remote refused it, and would refuse it again.

Fields

code: String

Stable code, never free text.

Unknown

The request left and no answer came back. The effect may exist (I15).

Fields

remote_ref: Option<String>

Reference the remote gave before it went quiet, when it gave one.
