A clean way to consume an input stream into a buffer using a sequence

Example.kt

fun inputStreamToTrimmedString(inputStream: InputStream): String {
    val baos = ByteArrayOutputStream()
    val buffer = ByteArray(128)
    inputStream.bufferedSequence(buffer) { bytesRead -> baos.write(buffer, 0, bytesRead) }
    return baos.toString("UTF-8").trim()
}

InputStreamExt.kt

import java.io.InputStream

fun InputStream.bufferedSequence(buffer: ByteArray, action: (bytesRead: Int) -> Unit) {
    this.use { inputStream ->
        generateSequence {
            when (val bytesRead = inputStream.read(buffer)) {
                -1 -> null
                else -> bytesRead
            }
        }.forEach(action)
    }
}
