Struct Return 

pub struct Return<'env, T: ReferenceType> { /* private fields */ }

FFI: Use Return<java::lang::Object> instead of jobject. This represents a (null?) JNI function call return value.

Unlike most Java reference types from this library, this can be null. Recommended constructors are crate::Local::into_return and Return::null.

FFI safe where a jobject is safe, assuming you match your types correctly.

Implementations

impl<'env, T: ReferenceType> Return<'env, T>

pub unsafe fn from_raw(object: jobject) -> Self

Wraps a raw JNI reference.

Safety

• If object is non-null, it must be a JNI local(?) reference to an instance of type T;
• object must keep valid for 'env lifetime; it is not owned by Local or any other wrapper that deletes the reference on Drop before the JNI native method call returns.

pub fn null() -> Self

Creates a null value to be returned from the JNI native method.

pub fn as_raw(&self) -> jobject

Returns the raw JNI reference pointer. Generally it should not be used.

Trait Implementations

impl<'env, T: ReferenceType> Default for Return<'env, T>

fn default() -> Self

This is a null value.
