Enum DnsError 

pub enum DnsError {
    NotUnderZone {
        host: String,
    },
    NotPublished {
        host: String,
    },
    Backend {
        host: String,
        message: String,
    },
}

Why a record could not be published or withdrawn.

Variants

NotUnderZone

The host is not one this provider is allowed to write.

A provider is scoped to a zone, and a request outside it is a configuration error, not a routing decision. Refusing loudly is the point: the alternative is a provider that quietly does nothing while the caller believes a challenge value is in place.

Fields

host: String

The host that was refused.

NotPublished

Nothing was published for this host, so there is nothing to withdraw.

Fields

host: String

The host that was absent.

Backend

The provider’s own request failed for a reason that is not zone containment — a network error, a malformed response, or exhausting a retry budget against a rate limit.

Fields

host: String

The host the failing request was for.

message: String

What the provider said went wrong.

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 PartialEq for DnsError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
