[−][src]Struct actix_web::error::InternalError
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 actix_web::fs::NamedFile; fn index(req: HttpRequest) -> Result<fs::NamedFile> { let f = NamedFile::open("test.txt").map_err(error::ErrorBadRequest)?; Ok(f) }
