Struct FetchPolicy

    pub request_timeout: Duration,
    pub max_chunks_per_peer: usize,
    pub failure_backoff_base: Duration,

Fields

attempts_per_peer: usize

request_timeout: Duration

max_chunks_per_peer: usize

failure_backoff_base: Duration

max_backoff: Duration

parallel_chunks: usize

Maximum number of chunk requests in flight at once across all peers. Higher values improve throughput when multiple peers are available.

max_stall_rounds: usize

Maximum consecutive stall loops (each separated by failure_backoff_base) before a download is aborted. A stall loop fires whenever no chunks are in-flight because every peer is currently in back-off. Default: 60 (≈ 18 s at the 300 ms default back-off base).

initial_reputations: HashMap<String, i32>

Optional seed reputation scores keyed by the peer’s canonical string ("<ip>:<port>:<transport>"). When present, a peer’s PeerRuntimeStats.score is initialised from this map so that historically reliable peers are tried before less-trusted ones.
