Hey, how do I use (non-reified) generics with the ktor client?

[ribesg]

This obviously doesn’t work

suspend fun <T> get(url: String): T =
        client.get(url)

Hi @ribesg, what kind of T do you want to use?

[ribesg]

I’m using kotlinx.serialization, so I guess any data class with the annotation?

[e5l]

Could you try

suspend fun <T> get(url: String): T =  
        client.get<T>(url)

?

[ribesg]

Doesn’t change anything, it suggests removing it and I still get Cannot use 'T' as reified type parameter. Use a class instead.

[ribesg]

Note that IDEA doesn’t say anything, it’s at compilation time that I get this error (which is weird)

It's a bug in IDE: https://youtrack.jetbrains.com/issue/KT-30265. You have to specify T explicitly when the parameter can't be reified cause of type erasure.

[ribesg]

Yes I know that but that doesn’t really help, it means you can’t wrap the ktor client in any class/object. I have to change my plans accordingly. I think I understand why it should not work.

You could use inline methods with reified with get like methods. Also you could use call or get<HttpResponse> explicitly.

Could you provide your project configuration in ticket https://youtrack.jetbrains.com/issue/KT-30265#comment=27-3322624 ?
