Enum CustomHostnameError 

pub enum CustomHostnameError {
    NotConfigured,
    Refused(HostnameRefusal),
    NotFound,
    AlreadyExists,
    Unauthorized,
    RateLimited,
    Rejected(String),
    Provider(String),
    Transport(String),
}

Custom-hostname failures. Every variant that carries the provider’s own text is scrubbed in Display (issue #235), the same way MailError’s is; Debug stays raw for tests.

Variants

NotConfigured

No zone or token is configured — answered before any request.

Refused(HostnameRefusal)

The hostname failed check_hostname; it was never sent to the provider.

NotFound

The provider has no such hostname.

AlreadyExists

The hostname is already claimed at the provider.

Unauthorized

The token was rejected or lacks permission.

RateLimited

Too many requests; retry later.

Rejected(String)

The provider refused the request (a 4xx with a message).

Provider(String)

The provider failed on its side (a 5xx, an unparseable envelope).

Transport(String)

The request never got an answer: a socket, a DNS failure, a timeout.

Trait Implementations

impl Clone for CustomHostnameError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomHostnameError

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

Formats the value using the given formatter.

impl Display for CustomHostnameError

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

Formats the value using the given formatter.

impl Eq for CustomHostnameError

impl Error for CustomHostnameError

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 CustomHostnameError

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

Equality operator ==.

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

Inequality operator !=.
