pub enum HeaderFetchOutcome {
Headers(Vec<BlockHeader>),
NoPeerAvailable,
PeerFailed,
}Expand description
Result of a block-header request, distinguishing why no headers came back so sync diagnostics can tell a connectivity problem from peers withholding data.
Variants§
Headers(Vec<BlockHeader>)
Headers were obtained from a peer.
NoPeerAvailable
No suitable peer was available to send the request to (e.g. no eth-capable peer connected, or all are busy / penalized).
PeerFailed
A peer was queried but returned no usable response (timeout, empty, or unchained).
