Trait HierExt

pub trait HierExt<'local> {
    // Required methods
    fn get_java_version(&mut self) -> Result<JavaVersion>;
    fn class_name<'other_local, T>(&mut self, class: T) -> Result<String>
       where T: Desc<'local, JClass<'other_local>>;
}

The additional definition for JNIEnv, used for define JClass caching (see [HierExt::lookup_class] and [HierExt::free_lookup]) and other useful class-related functions.

Required Methods

fn get_java_version(&mut self) -> Result<JavaVersion>

Gets the java version currently the jni environment is running on.

fn class_name<'other_local, T>(&mut self, class: T) -> Result<String>

where T: Desc<'local, JClass<'other_local>>,

Returns the given class’ class path.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
