调研方向

首先定位容器构造函数和 clear() 的实现,然后跟踪 insert()、find()、size() 和 ref() 等访问路径。确定应如何表示延迟初始化,以及哪些访问器必须触发它。当分配和初始化可以分离,同时每次首次使用都能安全地看到已初始化的容器时,即表示完成。

描述

type: feature request
Is your feature request related to a problem? Please describe.

Our current process involves memory allocation for a container within its constructor and instant initialization through the clear() function. This sequence happens immediately and is also enclosed within the constructor.

However, there are instances where it's beneficial to postpone the initialization step to a more appropriate time in the program flow.

Describe the solution you'd like

To facilitate this, we must implement a strategy allowing deferred initialization while ensuring the container is fully initialized before its first use. This is vital for maintaining data integrity and avoiding runtime errors.

One potential strategy could be an initialize-on-first-touch approach: Any function call that could potentially access the container's memory (like insert(), find(), size(), ref(), etc.) would first check a boolean member indicating whether the container has been initialized or not.

If the container is not yet initialized (i.e., the boolean is false), the clear() function would be invoked to initialize the container, thus ensuring it's ready for use.
