Struct actix_web::error::Error

pub struct Error { /* fields omitted */ }

General purpose actix web error.

An actix web error is used to carry errors from failure or std::error through actix 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 actix Error you can always get a ResponseError reference from it.

Methods

impl Error

pub fn cause(&self) -> &ResponseError

Deprecated since 0.6.0

: please use Error::as_response_error() instead

Deprecated way to reference the underlying response error.

pub fn as_fail(&self) -> &Fail

Returns a reference to the underlying cause of this Error as Fail

pub fn as_response_error(&self) -> &ResponseError

Returns the reference to the underlying ResponseError.

pub fn backtrace(&self) -> &Backtrace

Returns a reference to the Backtrace carried by this error, if it carries one.

This uses the same Backtrace type that failure uses.

pub fn downcast_ref<T: Fail>(&self) -> Option<&T>

Attempts to downcast this Error to a particular Fail type by reference.

If the underlying error is not of type T, this will return None.
