pub fn format_callback_result<T: Serialize, E: Serialize>(
result: Result<T, E>,
success_callback: CallbackFn,
error_callback: CallbackFn
) -> Result<String>
Expand description
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 checksuccess_callback
the function name of the Ok callback. Usually theresolve
of the JS Promise.error_callback
the function name of the Err callback. Usually thereject
of the JS Promise.
Note that the callback strings are automatically generated by the invoke
helper.
Examples
use tauri::api::ipc::{CallbackFn, format_callback_result};
let res: Result<u8, &str> = Ok(5);
let cb = format_callback_result(res, CallbackFn(145), CallbackFn(0)).expect("failed to format");
assert!(cb.contains(r#"window["_145"](5)"#));
let res: Result<&str, &str> = Err("error message here");
let cb = format_callback_result(res, CallbackFn(2), CallbackFn(1)).expect("failed to format");
assert!(cb.contains(r#"window["_1"]("error message here")"#));
