Make internal buffer aligned

This is the way to do it, right?

[nazar-pc]

Yes, though I'm wondering if any of the APIs used here actually require/benefit from std at all.

Probably a better approach to use the built in #[cfg_attr(repr(align(64)))] struct attribute instead. Ex:
https://rust-lang.github.io/hashbrown/src/crossbeam_utils/cache_padded.rs#94-127

If you can use new type then yes. You can also use this hack to align tuples and other data structures:

#[repr(align(64))]
struct CacheLineAligned;

struct S {
    something: [u8; 64],
    _align: CacheLineAligned,
}

This way even though the field is not used, its presence forces alignment of the whole struct. Depends on what you want exactly. aligned-vec is certainly unnecessary and even undesirable for fixed-size data structures.
