[][src]Struct actix_web::error::InternalError

pub struct InternalError<T> { /* 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 actix_web::fs::NamedFile;

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