Description
I often reach for heapless::Vec, but find myself having to write a custom slice wrapper due to peripheral alignment constraints have you had any thoughts about introducing a way to constrain the internal buffers alignment some how?
I found a quite nice crate called elain which I used in embedded-fatfs' block device wrapper. It allows the alignment of a field to be defined by a const generic parameter.

Research direction
Start by reviewing heapless's internal buffer representations and the alignment approach shown in embedded-fatfs's src/device.rs using elain. Define the API and supported data structures for constraining internal buffer alignment, then validate the design against peripheral alignment requirements and document the resulting behavior.
