Struct actix_web::error::Error

source ·
pub struct Error { /* private fields */ }
Expand description

General purpose Actix Web error.

An Actix Web error is used to carry errors from 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.

Implementations§

source§

impl Error

source

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

Returns the reference to the underlying ResponseError.

source

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

Similar to as_response_error but downcasts.

source

pub fn error_response(&self) -> HttpResponse

Shortcut for creating an HttpResponse.
