Enum LookupError 

#[non_exhaustive]
pub enum LookupError {
    BadQueryCount(usize),
    NameExists,
    ResponseCode(ResponseCode),
    NetError(NetError),
    RecursiveError(RecursorError),
    Io(Error),
}

A query could not be fulfilled

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.

BadQueryCount(usize)

The query had an invalid number of queries

NameExists

A record at the same Name as the query exists, but not of the queried RecordType

ResponseCode(ResponseCode)

There was an error performing the lookup

NetError(NetError)

Proto error

RecursiveError(RecursorError)

Available on crate feature recursor only.

Recursive Resolver Error

Io(Error)

An underlying IO error occurred

Implementations

impl LookupError

pub fn for_name_exists() -> Self

Create a lookup error, specifying that a name exists at the location, but no matching RecordType

pub fn is_nx_domain(&self) -> bool

This is a non-existent domain name

pub fn is_no_records_found(&self) -> bool

Returns true if no records were returned

pub fn into_soa(self) -> Option<Box<Record<SOA>>>

Returns the SOA record, if the error contains one

pub fn authorities(&self) -> Option<Arc<[Record]>>

Return authority records

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, __formatter: &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.
