I won't use err as a variable name here, as the type is unknown.
I would update the signature of all Just* methods
But it's the way must was written, so …

This is a reasonable suggestion, maybe I can adjust must along with it.

How do you feel about changing err to failure?

Naming is a pain.

Hi @yuweiweiouo and thanks for your first contribution. About the naming, At first, I thought that "Just" was referring to the reactive programming helper that creates a stream of N elements. Can you suggest other names?

Hi @samber, |

Was it merged or abandoned? |
Since it has been idle for too long and there has been no response, I believe this PR will not be accepted, so I closed it for now |
Summary
This PR introduces a new helper function named
EmptyOnErroralong withEmptyOnError1toEmptyOnError6. These functions are designed to safely retrieve values while ignoring errors, ensuring that in the case of an error, empty values are returned instead of triggering a panic.Motivation
In many scenarios, developers may only be interested in retrieving a value and are willing to ignore potential errors without risking a panic. The existing
Musthelper function, while useful, panics when an error is encountered, which might not always be desirable. TheEmptyOnErrorhelper and its variants (EmptyOnError1toEmptyOnError6) provide a safer alternative by returning empty values in case of an error.Unlike
Must, which can handle zero return values,EmptyOnErrorfocuses solely on the values returned by a function. Therefore, there is noEmptyOnError0variant, as it would be redundant.
