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

No records were found for a query

Fields of NoRecordsFound

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

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

Trait Implementations

impl Clone for ResolveErrorKind

fn clone(&self) -> Self

Returns a copy of the value.

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

Formats the value using the given formatter.

impl Display for ResolveErrorKind

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

Formats the value using the given formatter.

impl Error for ResolveErrorKind

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
