Expand description

The error kind for errors that get returned in the crate

Variants

`Message(&'static str)`

An error with an arbitrary message, referenced as &’static str

`Msg(String)`

An error with an arbitrary message, stored as String

`NoRecordsFound`

Fields

query: Query

The query for which no records were found.

soa: Option<SOA>

If an SOA is present, then this is an authoritative response.

negative_ttl: Option<u32>

negative ttl, as determined from DnsResponse::negative_ttl this will only be present if the SOA was also present.

response_code: ResponseCode

ResponseCode, if NXDOMAIN, the domain does not exist (and no other types). If NoError, then the domain exists but there exist either other types at the same label, or subzones of that label.

trusted: bool

If we trust NXDOMAIN errors from this server

No records were found for a query

`Io(Error)`

An error got returned from IO

`Proto(ProtoError)`

An error got returned by the trust-dns-proto crate

`Timeout`

A request timed out
