04/10/2019, 7:30 AMHello folks, I am currently working on a multiplatform library, targeting jvm and native, involving some hashing. For that I need a
ByteArrayStringString.toByteArray()a

04/10/2019, 7:40 AM Copy code
expect fun String.toByteArray(): ByteArrayt

04/10/2019, 7:41 AMThanks @addamsson, but how would you implement this using kotlin/native?

04/10/2019, 7:42 AMI'd suggest a different name though so that you can delegate to
toByteArrayI use
TODO()t

04/10/2019, 7:44 AMlol
okay, maybe a question for #kotlin-native then?

04/10/2019, 7:45 AMon a more serious note i'd take a look at the jvm implementation
Copy code
/**
* Encodes the contents of this string using the specified character set and returns the resulting byte array.
* @sample samples.text.Strings.stringToByteArray
*/
@kotlin.internal.InlineOnly
public inline fun String.toByteArray(charset: Charset = Charsets.UTF_8): ByteArray = (this as java.lang.String).getBytes(charset) Copy code
public byte[] getBytes(Charset charset) {
if (charset == null) throw new NullPointerException();
return StringCoding.encode(charset, value, 0, value.length);
}i'm not sure about the licensing though
you can't copy it verbatim probably

and was hoping for another answer ^^

04/10/2019, 7:47 AMI think you can argue that if you remove the java specific parts like the system calls for security
you're good to go
😞
welcome to the fertile grounds of Kotlin common
you just have to bring your own seeds 😄

addamsson
04/10/2019, 7:57 AMgood idea

i'll have to do #kotlin-native targets at some point
