Enum FetchOutcome

Source

pub enum FetchOutcome {
    Block(Vec<u8>),
    Missing,
}

Expand description

Per-CID outcome from a Bitswap block request.

The public contract is intentionally narrow: either the peer delivered the bytes for the CID or it did not. A peer signalling DONT_HAVE and a peer staying silent for a CID are both surfaced as FetchOutcome::Missing; callers needing a different policy must implement it over FetchOutcome.

Variants§

§

Block(Vec<u8>)

Peer returned bytes for the requested CID.

§

Missing

Peer did not deliver bytes for this CID.

Covers the peer explicitly answering DONT_HAVE, the peer answering HAVE without bytes, and the peer not acknowledging the CID at all. From the caller’s perspective these are equivalent: no block was delivered.
