Expand description

The possible errors of a Transport wrapped transport.

Variants§

§

Transport(TErr)

The underlying transport encountered an error.

§

ResolveError(ResolveError)

DNS resolution failed.

§

MultiaddrNotSupported(Multiaddr)

DNS resolution was successful, but the underlying transport refused the resolved address.

§

TooManyLookups

DNS resolution involved too many lookups.

DNS resolution on dialing performs up to 32 DNS lookups. If these are not sufficient to obtain a fully-resolved address, this error is returned and the DNS records for the domain(s) being dialed should be investigated.
