Struct Error

#[non_exhaustive]
pub struct Error {
    pub kind: Box<ErrorKind>,
    pub backtrack: Option<ExtBacktrace>,
}

The error type for errors that get returned in the crate

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: Box<ErrorKind>

Kind of error that occurred

backtrack: Option<ExtBacktrace>

Available on crate feature backtrace only.

Backtrace to the source of the error

Implementations

impl Error

pub fn kind(&self) -> &ErrorKind

Get the kind of the error

pub fn into_kind(self) -> ErrorKind

Take kind from the Error

pub fn is_nx_domain(&self) -> bool

Returns true if the domain does not exist

pub fn is_no_records_found(&self) -> bool

Returns true if no records were returned

pub fn is_timeout(&self) -> bool

Returns true if a query timed out

pub fn into_soa(self) -> Option<Box<Record<SOA>>>

Returns the SOA record, if the error contains one

pub fn authorities(self) -> Option<Arc<[Record]>>

Return additional records

pub fn recursion_exceeded( limit: Option<u8>, depth: u8, name: &Name, ) -> Result<(), Error>

Test if the recursion depth has been exceeded, and return an error if it has.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
