Enum ResourceId 

#[non_exhaustive]
pub enum ResourceId {
    Init,
    Part {
        msn: u64,
        part: u64,
    },
    Segment {
        msn: u64,
    },
}

Identifies one fetchable resource: the initialisation segment, a Low-Latency HLS partial segment (“part”, RFC 8216bis §4.4.4.9), or a whole media segment. Used to correlate an Action::FetchResource with the matching crate::client::HlsClient::on_resource call.

Part/Segment are keyed by Media Sequence Number (RFC 8216 §4.3.3.2) + (for parts) the 0-based Part Index within that segment — stable identity independent of the URI, since a delta/blocking reload can re-describe the same resource with the same URI more than once.

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.

Init

The Media Initialisation Section (EXT-X-MAP, RFC 8216bis §4.4.4.5).

Part

One partial segment (RFC 8216bis §4.4.4.9): msn’s Media Sequence Number, part its 0-based Part Index.

Fields

msn: u64

Media Sequence Number of the parent (possibly still-open) segment.

part: u64

0-based Part Index within that segment.

Segment

One whole media segment (RFC 8216 §4.3.3, non-LL full-segment fallback — a segment whose parts were never individually fetched).

Fields

msn: u64

Media Sequence Number.
