Kotlinコンパイラにあると思われるこの紛らわしいエラーが発生しました。コードを変更してもかまいませんが、実際に何か間違ったことをしたかどうかを把握しようとしています. 問題が発生しているコードは次のとおりだと思います。
inline fun <T> fiberListener(bufferSize: Int = 50,
policy: Channels.OverflowPolicy = Channels.OverflowPolicy.BACKOFF,
singleProducer: Boolean = true,
singleConsumer: Boolean = true,
crossinline action: (T) -> Unit): SendPort<T> {
val channel = Channels.newChannel<T>(bufferSize, policy, singleProducer, singleConsumer)
fiber { channel.forEach(action) }
return channel
}
これ以上何を言うべきかわかりませんが、これをインラインでなくすることはできますが、このコードは機能するはずです。GradleでKotlin 1.0.4を使用しています。別の注意点として、これが実際にパフォーマンスの向上をもたらすインライン化に肯定的ではありません。クロスインライン化についてはまだ少し不明です。しかし、どちらの方法でもうまくいくようで、この内部エラーを除いてIDEまたはコンパイラエラーは発生しません。
