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