Function presser::copy_to_offset_with_align_exact

pub fn copy_to_offset_with_align_exact<T: Copy, S: Slab + ?Sized>(
    src: &T,
    dst: &mut S,
    start_offset: usize,
    min_alignment: usize
) -> Result<CopyRecord, Error>

Copies src into the memory represented by dst starting at exactly start_offset bytes past the start of dst and with minimum alignment min_alignment. If the requested parameters would be violated by computed alignment requirements, an error will be returned.

• start_offset is the offset into the allocation represented by dst, in bytes, where the first byte of the copied data will be placed. If the requested start offset does not satisfy computed alignment requirements, an error will be returned and no data will be copied.
• min_alignment is the minimum alignment that you are requesting the copy be aligned to. The copy may be aligned greater than min_alignment depending on the alignment requirements of T (the actual alignment will be the greater of the two between align_of::<T>() and min_align.next_power_of_two()).

Safety

This function is safe on its own, however it is very possible to do unsafe things if you read the copied data in the wrong way. See the crate-level Safety documentation for more.
