Enum FailureClass 

#[non_exhaustive]
pub enum FailureClass {
    Retry {
        attempt: u32,
        kind: FailureKind,
    },
    GiveUp,
    NotYetAvailable {
        retry_at_us: u64,

    Expired,
    SegmentSkipped,
    EndTail,
}

What the caller does after a failure.

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.

Retry

Back off (the adapter owns the arithmetic, Retry-After included) and call super::DashClient::retry. attempt is the 1-based count of consecutive failures of this resource.

Fields

attempt: u32

Consecutive failures including this one.

kind: FailureKind

Why.

GiveUp

The failure count reached the configured cap: the presentation has ended with an super::Output::Fatal.

NotYetAvailable

A live segment requested before it exists (a 425, or a 404/410 inside the early-grace window): not counted. The client asks for it again from super::DashClient::poll at retry_at_us; the caller does nothing.

Fields

retry_at_us: u64

Monotonic microseconds at which the segment is requested again.

Expired

A live segment that left the time-shift window before it was fetched: not counted and not retried. The client continues at the oldest segment still available and marks the gap with a Discontinuity.

SegmentSkipped

A live segment given up on after the configured number of consecutive failures: super::Output::SegmentLost and a Discontinuity follow.

EndTail

The resource is the missing tail of a Period (DESIGN section 5.5 and the multi-period decision in the crate README): nothing to retry, nothing counted, playback continues.
