Function format_callback_result

pub fn format_callback_result<T: Serialize, E: Serialize>(
    result: Result<T, E>,
    success_callback: String,
    error_callback: String,
) -> Result<String>

Formats a Result type to its Promise response. Useful for Promises handling. If the Result is_ok(), the callback will be the success_callback function name and the argument will be the Ok value. If the Result is_err(), the callback will be the error_callback function name and the argument will be the Err value.

• result the Result to check
• success_callback the function name of the Ok callback. Usually the resolve of the JS Promise.
• error_callback the function name of the Err callback. Usually the reject of the JS Promise.

Note that the callback strings are automatically generated by the promisified helper.

Examples

use tauri_api::rpc::format_callback_result;
let res: Result<u8, &str> = Ok(5);
let cb = format_callback_result(res, "success_cb".to_string(), "error_cb".to_string()).expect("failed to format");
assert!(cb.contains(r#"window["success_cb"](5)"#));

let res: Result<&str, &str> = Err("error message here");
let cb = format_callback_result(res, "success_cb".to_string(), "error_cb".to_string()).expect("failed to format");
assert!(cb.contains(r#"window["error_cb"]("error message here")"#));
