Struct SignalError 

pub struct SignalError { /* private fields */ }

Error a receiver returns to fail the operation.

Build one from a message (SignalError::new) or from any error (SignalError::from_error, or ? on an OrmError). The text is logged and never returned to HTTP clients.

Implementations

impl SignalError

pub fn new(message: impl Into<String>) -> Self

A failure described by message.

pub fn from_error(error: impl Error + Send + Sync + 'static) -> Self

A failure caused by error, which is kept as the source.

pub fn message(&self) -> &str

The failure message.

Trait Implementations

impl Debug for SignalError

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

Formats the value using the given formatter.

impl Display for SignalError

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

Formats the value using the given formatter.

impl Error for SignalError

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 From<OrmError> for SignalError

fn from(error: OrmError) -> Self

Converts to this type from the input type.

impl From<SignalError> for OrmError

fn from(source: SignalError) -> Self

Converts to this type from the input type.
