Enum trust_dns_server::authority::LookupError

#[non_exhaustive]
pub enum LookupError {
    NameExists,
    ResponseCode(ResponseCode),
    ResolveError(ResolveError),
    Io(Error),
}

A query could not be fulfilled

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NameExists

A record at the same Name as the query exists, but not of the queried RecordType

ResponseCode(ResponseCode)

There was an error performing the lookup

ResolveError(ResolveError)

This is supported on crate feature tokio-runtime only.

Resolve Error

Io(Error)

An underlying IO error occurred

Implementations

impl LookupError

pub fn as_name_exists_mut(&mut self) -> Option<()>

Optionally returns references to the inner fields if this is a LookupError::NameExists, otherwise None

pub fn as_name_exists(&self) -> Option<()>

Optionally returns references to the inner fields if this is a LookupError::NameExists, otherwise None

pub fn as_response_code_mut(&mut self) -> Option<&mut ResponseCode>

Optionally returns mutable references to the inner fields if this is a LookupError::ResponseCode, otherwise None

pub fn as_response_code(&self) -> Option<&ResponseCode>

Optionally returns references to the inner fields if this is a LookupError::ResponseCode, otherwise None

pub fn into_response_code(self) -> Result<ResponseCode, Self>

Returns the inner fields if this is a LookupError::ResponseCode, otherwise returns back the enum in the Err case of the result

pub fn as_resolve_error_mut(&mut self) -> Option<&mut ResolveError>

Optionally returns mutable references to the inner fields if this is a LookupError::ResolveError, otherwise None

pub fn as_resolve_error(&self) -> Option<&ResolveError>

Optionally returns references to the inner fields if this is a LookupError::ResolveError, otherwise None

pub fn into_resolve_error(self) -> Result<ResolveError, Self>

Returns the inner fields if this is a LookupError::ResolveError, otherwise returns back the enum in the Err case of the result

pub fn as_io_mut(&mut self) -> Option<&mut Error>

Optionally returns mutable references to the inner fields if this is a LookupError::Io, otherwise None

pub fn as_io(&self) -> Option<&Error>

Optionally returns references to the inner fields if this is a LookupError::Io, otherwise None

pub fn into_io(self) -> Result<Error, Self>

Returns the inner fields if this is a LookupError::Io, otherwise returns back the enum in the Err case of the result

impl LookupError

pub fn for_name_exists() -> Self

Create a lookup error, specifying that a name exists at the location, but no matching RecordType

pub fn is_name_exists(&self) -> bool

True if other records exist at the same name, but not the searched for RecordType

pub fn is_nx_domain(&self) -> bool

This is a non-existent domain name

pub fn is_refused(&self) -> bool

This is a non-existent domain name

Trait Implementations

impl Debug for LookupError

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

Formats the value using the given formatter.

impl Display for LookupError

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

Formats the value using the given formatter.

impl Error for LookupError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
