Struct Error 

pub struct Error { /* private fields */ }

Why a run, a compile or a function failed.

Implementations

impl Error

pub fn service( code: impl Into<Cow<'static, str>>, message: impl Into<Cow<'static, str>>, ) -> Self

An error carrying a function’s own code.

pub fn kind(&self) -> &ErrorKind

The class of the error.

pub fn message(&self) -> &str

The human-readable message.

pub fn with_retryable(self, yes: bool) -> Self

Overrides whether a retry may succeed.

pub fn with_source(self, source: impl Error + Send + Sync + 'static) -> Self

Attaches the error that caused this one.

pub fn is_retryable(&self) -> bool

May a retry succeed? A timeout says yes unless told otherwise; everything else says no.

pub fn wrap(self, context: impl Display) -> Self

Prefixes the message with context, keeping kind, retryability and source.

pub fn code(&self) -> &str

The recorded code for this error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<&Error> for ErrorRecord

fn from(error: &Error) -> Self

Converts to this type from the input type.

impl Serialize for Error

Writes the error as {"code", "message", "retryable"}: Error::code, Error::message and Error::is_retryable, in that order.

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
