Stack/value variable length arrays without heap fallback.

Pros:

  • Maybe sound?
  • Better than what you'll write.

Cons:

  • History of unsoundness (0.4.10 and earlier)
  • Disturbing amounts of unsafe

Cargo.toml+1feature "serde-1" -> "serde", 2018 edition, drop cruft

README.rst0"(not yet released)" no longer accurate.
benches/extend.rs+1+black_box
build.rs+1Dropped?
src/array.rs+1Improved safety docs, although could use more explaination of what relies on the invariants. () and bool indexing for 1/2-len arrays.
src/array_string.rs0mem::zeroed -> MaybeUninitCopy::uninitialized. Lots of Copy constraints, one transmute -> from_utf8_unchecked_mut (safer).
src/lib.rs0truncate now unsafe (but sound), new try_extend_from_slice is unsafe (but sound). ArrayVec::extend ZST handling is obtuse, would be unsound in C++, but I believe sound in Rust, maybe?
