连续内存分配算法: 使用 Buddy System 来实现: 这里可以试着调用 Buddy System Allocator 的轮子: 操作系统动态分配内存所用的堆大小(8M) #[global_allocator]:可以为全局需要用到堆的地方分配空间。 #[alloc_error_handler]:空间分配错误的回调 动态内存分配测试 ...

The responsibility of an allocator is to manage the available heap memory. It needs to return unused memory onalloccalls and keep track of memory freed bydeallocso that it can be reused again. Most importantly, it must never hand out memory that is already in use somewhere else because this...
