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)

NoRecordsFound

No records were found for a query

Fields of NoRecordsFound

query: Query	The query for which no records were found.
valid_until: Option<Instant>	A deadline after which the the NXDOMAIN response is no longer valid, and the nameserver should be queried again.

Io

Timeout

A request timed out

Trait Implementations

impl Eq for ResolveErrorKind

impl PartialEq for ResolveErrorKind

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for ResolveErrorKind

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

Formats the value using the given formatter.

impl Fail for ResolveErrorKind

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where     D: Display + Send + Sync + 'static,

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

Important traits for Causes<'f>

impl<'f> Iterator for Causes<'f> type Item = &'f (Fail + 'static);

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for ResolveErrorKind

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

Formats the value using the given formatter.

impl Clone for ResolveErrorKind

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<ResolveErrorKind> for ResolveError

fn from(kind: ResolveErrorKind) -> ResolveError

Performs the conversion.
