Converting exceptions to null?

[rnikander]

Is there an idiomatic way to run a piece of code and convert exceptions to null? Eg…

// Returns Number or throws
parse(str)
// Returns Number?
catchToNull { parse(str) }

I could write catchToNull easily enough. Just wondering if it’s already there under a different name.

We have runCatching that would give you a Result. Maybe runOrNull would be a more kotlinesque name?

catchToNull { parse(str) }

runCatching { parse(str) }.getOrNull()

Is the closest
