Struct Error

pub struct Error { /* private fields */ }

General purpose scrappy web error.

An scrappy web error is used to carry errors from failure or std::error through scrappy in a convenient way. It can be created through converting errors with into().

Whenever it is created from an external object a response error is created for it that can be used to create an http response from it this means that if you have access to an scrappy Error you can always get a ResponseError reference from it.

Implementations

impl Error

pub fn as_response_error(&self) -> &dyn ResponseError

Returns the reference to the underlying ResponseError.

pub fn as_error<T: ResponseError + 'static>(&self) -> Option<&T>

Similar to as_response_error but downcasts.

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 cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

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 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.
