Enum LookupError 

#[non_exhaustive]
pub enum LookupError {
    ParseError {
        source: ParseError,
        meta: Meta,
    },
    LookupFailed {
        source: DnsError,
        meta: Meta,
    },
}

Potential errors related to DNS endpoint address lookups.

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.

ParseError

Trait Implementations

impl Debug for LookupError

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

Formats the value using the given formatter.

impl Display for LookupError

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

Formats the value using the given formatter.

impl Error for LookupError

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<DnsError> for LookupError

fn from(source: DnsError) -> Self

Converts to this type from the input type.

impl From<LookupError> for AnyError

fn from(value: LookupError) -> AnyError

Converts to this type from the input type.

impl From<ParseError> for LookupError

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl StackError for LookupError

fn as_std(&self) -> &(dyn Error + Send + Sync + 'static)

Returns this error as a std error reference.

fn into_std(self: Box<Self>) -> Box<dyn Error + Send + Sync>

Returns this error as a std error.

fn as_dyn(&self) -> &dyn StackError

Returns this error as a dyn StackError.

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

Returns the next source in the chain, if any.

fn meta(&self) -> Option<&Meta>

Returns metadata captured at creation time, if available.

fn source(&self) -> Option<ErrorRef<'_>>

Returns the next source in the chain, if any.

fn is_transparent(&self) -> bool

Returns whether this error is transparent and should be skipped in reports.

fn as_ref(&self) -> ErrorRef<'_>

Returns this error as an [ErrorRef].

fn stack(&self) -> Chain<'_>

Returns an iterator over this error followed by its sources.

fn sources(&self) -> Chain<'_>

Returns an iterator over sources of this error (skipping self).

fn report(&self) -> Report<'_>

Returns a [Report] to output the error with configurable formatting.
