Enum trust_dns_server::authority::LookupError

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

Available on crate feature resolver only.

Resolve Error

RecursiveError(Error)

Available on crate feature recursor only.

Recursive Resolver Error

Io(Error)

An underlying IO error occurred

Implementations

impl LookupError

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

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 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
