Trait TaskExt 

pub trait TaskExt<T, E> {
    // Required methods
    fn detach_and_log_err(self, cx: &App);
    fn detach_and_log_err_with_backtrace(self, cx: &App);
}

Extension methods for tasks that produce a Result.

The methods log a failure instead of dropping it silently, so use them for work that you start and don’t wait for.

Examples

use gpui::{TaskExt, TestApp};

let mut app = TestApp::new();
app.update(|cx| {
    let save = cx.background_executor().spawn(async { Err::<(), _>("disk full") });
    save.detach_and_log_err(cx);
});

Required Methods

fn detach_and_log_err(self, cx: &App)

Runs the task to completion in the background. If it fails, the error is written to the log.

fn detach_and_log_err_with_backtrace(self, cx: &App)

Like TaskExt::detach_and_log_err, but logs the error with Debug formatting, so an anyhow::Error includes its backtrace. Use it when you need the backtrace, and the other method otherwise.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
