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 copy 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<'a> From<&'a Error> for ErrorCode

fn from(err: &'a Error) -> ErrorCode

Converts to this type from the input type.

impl From<Error> for ErrorCode

fn from(err: Error) -> ErrorCode

Converts to this type from the input type.

impl From<Error> for ErrorCode

fn from(err: Error) -> ErrorCode

Converts to this type from the input type.

impl From<ErrorCode> for Errno
