Function error_handler_wrapper

pub fn error_handler_wrapper(
    res: Result<Vec<String>, u16>,
) -> Result<Vec<String>, String>

Handle HTTP status codes errors and “no SSH keys” error.

TODO: Add context about username and service to improve error messages

Errors

The function use the crate exitfailure to print a better error message on exit. It returns an error string that contains the error description on:

• Input vector length is 0
• Input has no Ok result, but has error code:
  • 404 HTTP Status Code -> Usually it means that the user doesn’t exists
  • 1001 Internal error -> GitHub username is invalid (see https://github.com/shinnn/github-username-regex)
  • 1002 Internal error -> GitHub API response could not be parsed
  • Every other status code -> Unrecognized HTTP status code (i.e. 500, 501, etc.)

Assuming that a 2XX response will always have an Ok value, so it will never reach ‘error matching’

Examples

No errors

use superkeyloader_lib::error_handler_wrapper;

let data = vec!("key1".to_string(), "key1".to_string());
let input = Ok(data.clone());
let output = error_handler_wrapper(input);

assert_eq!(data, output.unwrap());

Missing user (404 status code)

use superkeyloader_lib::error_handler_wrapper;

let error_code: u16 = 404;
let input = Err(error_code);
let output = error_handler_wrapper(input);

assert!(output.is_err());

let expected_output = String::from("Wrong username");
let error_message = output.err().unwrap();

assert!(error_message.contains(&expected_output));
