Description:
The website provides detailed documentation on the kernel's Vec type in Rust, specifically focusing on the kernel::alloc::kvec module. The Vec type is described as a contiguous growable array with contents allocated using the kernel's allocators like Kmalloc, Vmalloc, or KVmalloc. It is parameterized by the type T and an allocator A. The Vec type handles non-zero-sized values by using the specified allocator for allocation. For zero-sized types, the Vec's pointer must be dangling_mut::<T> with no memory allocation. The Vec struct consists of fields like a pointer to the backing buffer, capacity, length, and the Allocator type used for allocation and deallocation.

I was disappointed with the documentation on kernel.org regarding the Vec type in Rust. It was too complex and lacked practical examples to help beginners understand.
