Crate api_err 

Errors for conveniently attaching status codes to error cases.

use api_err::{CategoryExt, Context};

fn add_one(request: &str) -> api_err::Result<String> {
   let input = request.parse::<i64>().bad_request()?;
   let output = input.checked_add(1).context("Input too large").bad_request()?;
   Ok(output.to_string())
}

Errors without a category attached default to the “Internal Server”-like error.
