Trait Implementations

impl Clone for ErrorMessage

fn clone(&self) -> ErrorMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorMessage

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

Formats the value using the given formatter.

impl Display for ErrorMessage

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

Formats the value using the given formatter.

impl Error for ErrorMessage

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 ErrorMessage> for ByteString

fn from(msg: &'a ErrorMessage) -> Self

Converts to this type from the input type.

impl From<&'static str> for ErrorMessage

fn from(value: &'static str) -> Self

Converts to this type from the input type.

impl From<ByteString> for ErrorMessage

fn from(value: ByteString) -> Self

Converts to this type from the input type.

impl From<ErrorMessage> for ByteString

fn from(msg: ErrorMessage) -> Self

Converts to this type from the input type.

impl From<String> for ErrorMessage

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorMessage

fn eq(&self, other: &ErrorMessage) -> 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.
