Error type for DNS zone payloads and record validation.

Variants

NestedTooDeeply

The DNS JSON payload is nested too deeply.

ParseError(Error)

The DNS JSON payload could not be parsed.

TooManyRecords

The zone contains more than the maximum allowed number of records.

InvalidLabelLength(String)

A DNS label has an invalid length (empty or >62 chars).

InvalidLabelCharacters(String)

A DNS label contains invalid characters.

InvalidCnameConfiguration(String)

A CNAME record was provided alongside other records for the same label.

TxtRecordTooLong(String)

A TXT record exceeds the maximum allowed length (255 bytes).

InvalidCnameTarget(String)

A CNAME target is empty or too long.

InvalidPeerId(String)

A PeerId string could not be parsed into a valid libp2p PeerId.

InvalidKid(String)

A KID string does not start with the required did:kin: prefix.

InvalidIpfsCid(String)

An IPFS CID string is invalid.

Implementations

impl DnsError

pub fn code(&self) -> &'static str

Stable protocol error code.

pub fn error_type_uri(&self) -> String

RFC 7807 type URI for this error.

pub fn severity(&self) -> Severity

Severity level for logging and monitoring.

pub fn is_retryable(&self) -> bool

Trait Implementations

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 Eq for DnsError

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<Error> for DnsError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for DnsError

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

Equality operator ==.
