How can I make an extension function to wrap this Java mappingFunction ...:
@Nullable V get(@NonNull K key, @NonNull Function<? super K, ? extends V> mappingFunction);

I really don't know what could be wrong:

suspend inline fun <reified K : Any, reified V : Any> Cache<K, V>.get(key: K, crossinline mappingFunction: suspend (K) -> V): V? =
	get(key) { runBlocking { mappingFunction(it) } }

it's probably related to the generics... 🤕

Member functions have precedence.

Oh but this is suspend. Nvm.

I think you're right... I tried renaming it and the IDEA did except it...

[dave08]

I just wonder why... to the compiler the params are different...?

[Dominaezzz]

When you call it, do you actually use suspension?

[dave08]

yes

[Dominaezzz]

Hmm, to save you time, just rename it.

[dave08]

Yup, that's what I did, thanks for the info about member functions... 🙂
