int a[n];

与

int * a;
a = malloc(n * sizeof(int));

谁能分别解释一下这两种方法的优缺点？（效率、安全性等）

我是异步编程的新手，因此努力解决不同方法的行为差异。

考虑 tokio 在 github 存储库 chat.rs 中给出的示例：

// snip
    loop {
        tokio::select! {
            // A message was received from a peer. Send it to the current user.
            Some(msg) = peer.rx.recv() => {
                // do something
            }

                // A message was received from the current user, we should
                // broadcast this message to the other users.
                Some(Ok(msg)) => {
                    // do something
                }
                Some(Err(e)) => {
                    // handle error
                }
                // The stream …
