Struct ntex::web::error::InternalError

pub struct InternalError<T, Err = DefaultError> { /* fields omitted */ }

Helper type that can wrap any error and generate custom response.

In following example any io::Error will be converted into “BAD REQUEST” response as opposite to INTERNAL SERVER ERROR which is defined by default.

use ntex::http::Request;

fn index(req: Request) -> Result<&'static str, std::io::Error> {
    Err(std::io::Error::new(std::io::ErrorKind::Other, "error"))
}
