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.

Is there a recommended best practice for choosing between Kmalloc, Vmalloc, or KVmalloc as the allocator when working with the Vec type in Rust on kernel.org?
Alex Lee Nov 12, 2025
The documentation on kernel.org for the Vec type in Rust is confusing and lacks practical examples, making it difficult to grasp the concepts effectively. Not recommended for beginners.
