Struct Error 

pub struct Error { /* private fields */ }

Error type for event source.

Implementations

impl Error

pub fn new(kind: ErrorKind, message: impl Into<Cow<'static, str>>) -> Self

Creates a new error with the given kind and message.

pub const fn kind(&self) -> ErrorKind

Returns the error kind.

pub fn message(&self) -> &str

Returns the error message.

pub fn context(&self) -> &[(&'static str, String)]

Returns the error context entries.

pub fn with_context(self, key: &'static str, value: impl ToString) -> Self

Adds a context entry to the error.

pub fn set_source(self, source: impl IntoErrorSource) -> Self

Attaches a error source.

pub fn source(&self) -> Option<&ErrorSource>

Returns the source error, if any.

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<ProtocolError> for Error

fn from(err: ProtocolError) -> Self

Converts to this type from the input type.

impl<E> From<StreamError<E>> for Error

where E: Error + Send + Sync + 'static,

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

Converts to this type from the input type.
