Struct SliceArcInnerForStatic

Source 
#[repr(C, align(16))]
struct SliceArcInnerForStatic {
    inner: ArcInner<[u8; 1]>,
}
Expand description

Struct to hold the static ArcInner used for empty Arc<str/CStr/[T]> as returned by Default::default.

Layout notes:

  • repr(align(16)) so we can use it for [T] with align_of::<T>() <= 16.
  • repr(C) so inner is at offset 0 (and thus guaranteed to actually be aligned to 16).
  • [u8; 1] (to be initialized with 0) so it can be used for Arc<CStr>.
