The error kind for errors that get returned in the crate

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future 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

NoConnections

No resolvers available

NoRecordsFound

No records were found for a query

Fields

query: Box<Query>

The query for which no records were found.

soa: Option<Box<Record<SOA>>>

If an SOA is present, then this is an authoritative response or a referral to another nameserver, see the negative_type field.

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) -> ResolveErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolveErrorKind

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

Formats the value using the given formatter.

impl Display for ResolveErrorKind

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

Formats the value using the given formatter.

impl Error for ResolveErrorKind

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<Error> for ResolveErrorKind

fn from(source: Error) -> ResolveErrorKind

Converts to this type from the input type.

impl From<ProtoError> for ResolveErrorKind

fn from(source: ProtoError) -> ResolveErrorKind

Converts to this type from the input type.

impl From<ResolveErrorKind> for ResolveError

fn from(kind: ResolveErrorKind) -> ResolveError

Converts to this type from the input type.
