Errors that may occur when sending an onion message.

Variants

Secp256k1(Error)

Errored computing onion message packet keys.

TooBigPacket

Because implementations such as Eclair will drop onion messages where the message packet exceeds 32834 bytes, we refuse to send messages where the packet exceeds this size.

TooFewBlindedHops

The provided Destination was an invalid BlindedMessagePath due to not having any blinded hops.

InvalidFirstHop(PublicKey)

The first hop is not a peer and doesn’t have a known SocketAddress.

PathNotFound

Indicates that a path could not be found by the MessageRouter.

This occurs when either:

• No path from the sender to the destination was found to send the onion message
• No reply path to the sender could be created when responding to an onion message

InvalidMessage

Onion message contents must have a TLV type >= 64.

BufferFull

Our next-hop peer’s buffer was full or our total outbound buffer was full.

GetNodeIdFailed

Failed to retrieve our node id from the provided NodeSigner.

UnresolvedIntroductionNode

The provided Destination has a blinded path with an unresolved introduction node. An attempt to resolve it in the MessageRouter when finding an OnionMessagePath likely failed.

BlindedPathAdvanceFailed

We attempted to send to a blinded path where we are the introduction node, and failed to advance the blinded path to make the second hop the new introduction node. Either NodeSigner::ecdh failed, we failed to tweak the current blinding point to get the new blinding point, or we were attempting to send to ourselves.

Trait Implementations

impl Clone for SendError

fn clone(&self) -> SendError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SendError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for SendError

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SendError

fn eq(&self, other: &SendError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
