Struct WebError 

pub struct WebError<St = (), Err = DefaultError>(/* private fields */);

Type-erased web error for the Err error domain.

Web services, middleware, and filters use WebError as their error type. It stores any error that implements WebResponseError for the same application state and error domain, and renders it with that implementation.

Implementations

impl<St: 'static, Err: 'static> WebError<St, Err>

pub fn from_err<E: WebResponseError<St, Err>>(err: E) -> Self

Create WebError from an error that can be rendered for this domain.

Trait Implementations

impl<St, Err> Debug for WebError<St, Err>

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

Formats the value using the given formatter.

impl<St, Err> Display for WebError<St, Err>

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

impl<St, Err> Error for WebError<St, Err>

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
