Struct Error 

pub struct Error<E> { /* private fields */ }

Implementations

impl<E> Error<E>

pub fn new<T>(error: T, service: &'static str) -> Self

where E: ErrorDiagnostic + From<T>,

pub fn set_service(self, name: &'static str) -> Self

Set response service

pub fn map<U, F>(self, f: F) -> Error<U>

where F: FnOnce(E) -> U,

Map inner error to new error

Keep same service and location

pub fn into_error(self) -> E

Get inner error value

Trait Implementations

impl<E: Clone> Clone for Error<E>

fn clone(&self) -> Error<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E> Deref for Error<E>

type Target = E

The resulting type after dereferencing.

fn deref(&self) -> &E

Dereferences the value.

impl<E> Display for Error<E>

where E: ErrorDiagnostic,

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

Formats the value using the given formatter.

impl<E> Error for Error<E>

where E: ErrorDiagnostic,

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<E> ErrorDiagnostic for Error<E>

where E: ErrorDiagnostic,

type Kind = <E as ErrorDiagnostic>::Kind

fn kind(&self) -> Self::Kind

Provides specific kind of the error

fn service(&self) -> Option<&'static str>

Provides a string to identify responsible service

fn signature(&self) -> &'static str

Provides a string to identify specific kind of the error

fn backtrace(&self) -> Option<&Backtrace>

Provides error call location

fn is_service(&self) -> bool

Check if error is service related

fn chain(self) -> ErrorChain<Self::Kind>

where Self: Sized,

impl<E: ErrorDiagnostic> From<E> for Error<E>

fn from(error: E) -> Self

Converts to this type from the input type.

impl<E, K> From<Error<E>> for ErrorChain<K>

where E: ErrorDiagnostic + Sized, E::Kind: Into<K>, K: ErrorKind,

fn from(err: Error<E>) -> Self

Converts to this type from the input type.

impl<E> PartialEq<E> for Error<E>

where E: PartialEq,

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

impl<E> PartialEq for Error<E>

where E: PartialEq,

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

impl<E> Eq for Error<E>

where E: Eq,
