Expand description

Error decoding an inbound snap protocol message from its framed bytes, or matching a response to its request.

Variants§

§

Empty

The payload was empty and carried no message id.

§

UnsupportedMessageId(u8, SnapVersion)

The message id is not valid for the negotiated snap version (e.g. the removed trie-node messages 0x06/0x07 under snap/2).

§

Rlp(Error)

Decoding the RLP message body failed.

§

UnsolicitedResponse

The response answers no request sent on this connection.

The response is rejected before its body is decoded.

Fields

§message_id: SnapMessageId

The message id of the response.

§request_id: u64

The request id the response carried.

§

ResponseExceedsRequest

A list in the response is longer than its request allows: more entries than requested, or more range proof nodes than two boundary paths can hold.

The response is rejected before its body is decoded.

Fields

§message_id: SnapMessageId

The message id of the response.

§request_id: u64

The request id the response carried.

§max_items: usize

The longest the list may be.
