How to use in multi-threaded(sync)

[sirodeneko]

I have a structure, then I will instantiate a unique one of it and pass it to sync to call the java method。

pub struct Hannanum {
    _jvm: Jvm,
    _instance: Instance,
}

but,compilation has failed.

   `*mut *const JNINativeInterface_` cannot be sent between threads safely
   = help: within `konlpy::KonlpyTokenizer`, the trait `Send` is not implemented for `*mut *const JNINativeInterface_`
   = note: required because it appears within the type `Jvm`

because I have to implement the 'Send' trait。 I don't know how to implement it safely。

The Jvm cannot be sent between threads because it contains JNI components that also cannot be sent between threads. All you need to do, is to attach the current thread to the Jvm, using:

let jvm: Jvm = Jvm::attach_thread().unwrap();
