Struct MxResolveError 

pub struct MxResolveError {
    pub kind: MxResolveFailure,
    pub message: String,
}

An MX resolution failure: its MxResolveFailure classification together with a human-readable message. Display writes message verbatim, which means {err} formatting (including anyhow!("{err}") and log output) reproduces that text. Conversion to anyhow::Error keeps this concrete type rather than erasing it: a caller holding the resulting anyhow::Error can recover the classification with downcast_ref::<MxResolveError>().

Fields

kind: MxResolveFailure

message: String

Implementations

impl MxResolveError

pub fn is_nxdomain(&self) -> bool

Whether the resolver returned NXDOMAIN for the name, for callers that need to single out that case without inspecting the message text.

Trait Implementations

impl Clone for MxResolveError

fn clone(&self) -> MxResolveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MxResolveError

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

Formats the value using the given formatter.

impl Display for MxResolveError

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

Formats the value using the given formatter.

impl Error for MxResolveError

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
