Struct java_spaghetti::Return

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

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.

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