Available on crate feature p3 only.

Lookup error codes.

Variants

Unknown = 0

Unknown error

AccessDenied = 1

Access denied.

POSIX equivalent: EACCES, EPERM

InvalidArgument = 2

name is a syntactically invalid domain name or IP address.

POSIX equivalent: EINVAL

NameUnresolvable = 3

Name does not exist or has no suitable associated IP addresses.

POSIX equivalent: EAI_NONAME, EAI_NODATA, EAI_ADDRFAMILY

TemporaryResolverFailure = 4

A temporary failure in name resolution occurred.

POSIX equivalent: EAI_AGAIN

PermanentResolverFailure = 5

A permanent failure in name resolution occurred.

POSIX equivalent: EAI_FAIL

Implementations

impl ErrorCode

pub fn name(&self) -> &'static str

pub fn message(&self) -> &'static str

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Error for ErrorCode

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 ErrorCode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
