Core Tryx - Lo — ContextQMD

Calls a function and returns false in case of error or panic. Variants cover callbacks returning 0 to 6 values.

ok := lo.Try(func() error {
    // return an error to mark failure
    return fmt.Errorf("boom")
})
// ok == false

ok = lo.Try0(func() {
    // panics are caught and return false
    panic("boom")
})
// ok == false

ok = lo.Try2(func() (int, error) {
    return 42, nil
})
// ok == true
