Errors that may occur during query evaluation.

Variants

Timeout

The query timed out.

Dns(Option<Box<dyn Error + Send + Sync>>)

A DNS error occurred, with source attached if available. The error source may come from the Lookup implementation and is therefore of an arbitrary error type.

LookupLimitExceeded

The lookup limit was exceeded.

PerMechanismLookupLimitExceeded

The per-mechanism lookup limit was exceeded.

VoidLookupLimitExceeded

The void lookup limit was exceeded.

RecursiveTemperror

A recursive query that failed with Temperror is being propagated.

RecursivePermerror

A recursive query that failed with Permerror is being propagated.

IncludeNoSpfRecord

An include mechanism targeted a domain with no SPF record.

InvalidName(String)

A target domain name was in an invalid format.

InvalidMacroInDomainSpec(Macro)

A domain specification contained an invalid macro.

Trait Implementations

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Error for EvalError

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.
