Enum DnsError 

#[non_exhaustive]
pub enum DnsError {
    ResponseCode(ResponseCode),
    NoRecordsFound(NoRecords),
    #[non_exhaustive]
    Nsec {
        query: Box<Query>,
        response: Box<DnsResponse>,
        proof: Proof,
    },
}

Semantic DNS errors

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.

ResponseCode(ResponseCode)

Received an error response code from the server

NoRecordsFound(NoRecords)

No records were found for a query

#[non_exhaustive]

Nsec

Available on crate feature __dnssec only.

No Records and there is a corresponding DNSSEC Proof for NSEC

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

query: Box<Query>

Query for which the NSEC was returned

response: Box<DnsResponse>

Response for which the NSEC was returned

proof: Proof

DNSSEC proof of the record

Implementations

impl DnsError

pub fn from_response(response: DnsResponse) -> Result<DnsResponse, Self>

A conversion to determine if the response is an error

Trait Implementations

impl Clone for DnsError

fn clone(&self) -> DnsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsError

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

Formats the value using the given formatter.

impl Display for DnsError

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

Formats the value using the given formatter.

impl Error for DnsError

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 NetError

fn from(source: DnsError) -> Self

Converts to this type from the input type.
