* I've got a situation where I would like to store a list of messages / variable length structures (something like `address: u8`, `length: u8`, `data: [u8; length]`)

I'd like to fit as many messages as possible into a fixed sized piece of memory. And I'd like to not waste any memory.

Are there any good alternatives to using an heap allocator like `heapless` ? (I don't really want to write yet another custom buffer in the name of efficiency/performance/etc.)

edit: `embedded-alloc`
