You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: guarded_box.rs
    path of file: ./repos/flutter_rust_bridge/frb_rust/src/dart_opaque/boxes
    
    the code of the file until where you have to start completion: use crate::misc::logs::log_warn_or_println;
use std::fmt::Debug;

/// Only allows manipulation of [inner] value when the [context] is the same
/// as the context when it is created.
///
/// It is a "black box" that nobody can open it otherwise.
#[derive(Debug)]
pub(crate) struct GuardedBox<T: Debug, C: GuardedBoxContext> {
    // `Option` is used for correct drop.
    inner: Option<T>,
    context: C,
}

pub(crate) trait GuardedBoxContext: Debug + Eq {
    fn curre
    
    fn drop(&mut self) {
        if self.inner.is_some() && !self.check_context() {
            if std::thread::panicking() {
                log_warn_or_println(
                    "GuardedBox.drop cannot drop data because the context is different. \
However, system is already panicking so we cannot panic twice. \
Therefore, we have to make a memory leak for the data.",
                );

                std::mem::forget(self.inner.take());
            } else {
                self.panic_because_context_failed()
            }
        }
    }
