Enum Delivered 

pub enum Delivered {
    Accepted,
    Rejected {
        status: u16,
        retry_after: Option<u64>,
    },
    Unreachable(String),
}

What happened to one delivery attempt.

Variants

Accepted

The receiver answered 2xx, which is the acknowledgement the spec asks for.

Rejected

It answered something else.

Fields

status: u16

retry_after: Option<u64>

What the receiver asked to be waited, in seconds, if it said.

A 429 or a 503 with Retry-After is a receiver naming its own recovery, and a sender that overrides it with a schedule of its own is choosing to be told twice. Honoured in preference to the worker’s backoff, and bounded there rather than here.

Unreachable(String)

It did not answer.

Implementations

impl Delivered

pub const fn is_permanent(&self) -> bool

Whether this answer will still be this answer after a wait.

410 Gone is the one status that means it: the receiver is stating that the resource is permanently absent, which is precisely a webhook endpoint that has been retired. Every other rejection is treated as transient, including 4xx — a 404 during a deploy, a 401 while a credential rotates and a 400 from a receiver mid-upgrade are all answers that change, and abandoning a run’s events on the first of them would lose more than a wasted retry costs.

pub const fn retry_after(&self) -> Option<u64>

The receiver’s own advice about when to come back.
