[−][src]Struct actix_web::error::Error
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[src]
pub fn cause(&self) -> &dyn ResponseError[src]
please use Error::as_response_error() instead
Deprecated way to reference the underlying response error.
pub fn as_fail(&self) -> &dyn Fail[src]
Returns a reference to the underlying cause of this Error as Fail
pub fn as_response_error(&self) -> &dyn ResponseError[src]
Returns the reference to the underlying ResponseError.
pub fn backtrace(&self) -> &Backtrace[src]
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>[src]
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.
