Chris Morgan 93511917c3 Rename UncheckedAnyExt, fix Extend, tweak things 
The *name* UncheckedAnyExt was ending up visible in docs, but it had
become an increasingly unpleasant name. “Downcast” is suitable, though,
being private, it’s not still not perfect. But there’s no point in
making it public, as people generally can’t implement it because of
coherence rules (I tried).

Plus documentation and style changes.

As for Extend, eh, that should ideally be in a different commit, but
it’s here now, and I’m the only one working on this code base in
general, so I permit myself to be slightly lazy from time to time.
Trouble was Downcast should never have had an Any supertrait, as it was
grossly misleading, leading to type_id giving `dyn Any`’s TypeId rather
than the underlying type’s.

Raw Blame History

1.0.0 (unreleased)

Planned once the dust of 1.0.0-beta.1 settles, since 1.0.0-beta.1 ended up being bigger than I’d earlier intended.

1.0.0-beta.2 (unreleased)

  • Fixed the broken Extend implementation added in 1.0.0-beta.1.

1.0.0-beta.1 (2022-01-25)

  • Removed anymap::any::Any in favour of just plain core::any::Any, since its Send/Sync story is now long stable.

    • This loses Any + Sync. CloneAny + Sync is also removed for consistency. (So Any + Sync is gone, but Any, Any + Send and Any + Send + Sync remain, plus the same set for CloneAny.)

  • anymap::any::CloneAny moved to anymap::CloneAny. With nothing public left in anymap::any, it is removed.

  • Relicensed from MIT/Apache-2.0 to BlueOak-1.0.0/MIT/Apache-2.0.

  • Increased the minimum supported version of Rust from 1.7.0 to 1.36.0.

  • no_std is now possible in the usual way (default Cargo feature 'std'), depending on alloc and hashbrown.

  • Removed the bench Cargo feature which was mostly to work around historical Cargo limitations, but was solved by moving benchmarks from src/lib.rs to benches/bench.rs even before those limitations were lifted. The benchmarks still won’t run on anything but nightly, but that don’t signify.

  • Implemented Default on Map (not just on RawMap).

  • Added Entry::{or_default, and_modify} (std::collections::hash_map parity).

  • Removed the anymap::raw wrapper layer around std::collections::hash_map, in favour of exposing the raw HashMap directly. I think there was a reason I did it that seven years ago, but I think that reason may have dissolved by now, and I can’t think of it and I don’t like the particular safe as_mut/unsafe insert approach that I used. Because of the hashbrown stuff, I have retained anymap::RawMap is an alias, and anymap::raw_hash_map too. The end result of this is that raw access can finally access things that have stabilised since Rust 1.7.0, and we’ll no longer need to play catch-up.

  • Worked around the spurious where_clauses_object_safety future-compatibility lint that has been raised since mid-2018. If you put #![allow(where_clauses_object_safety)] on your binary crates for this reason, you can remove it.

0.12.1 (2017-01-20)

  • Remove superfluous Clone bound on Entry methods (#26)
  • Consistent application of #[inline] where it should be
  • Fix bad performance (see 724f94758d for details)

0.12.0 (2016-03-05)

  • Ungate drain iterator (stable from Rust 1.6.0)
  • Ungate efficient hashing (stable from Rust 1.7.0)
  • Remove unstable Cargo feature (in favour of a bench feature for benchmarking)

0.11.2 (2016-01-22)

  • Rust warning updates only

0.11.1 (2015-06-24)

  • Unstable Rust compatibility updates

0.11.0 (2015-06-10)

  • Support concurrent maps (Send + Sync bound)
  • Rename nightly feature to unstable
  • Implement Debug for Map and RawMap
  • Replace clone Cargo feature with arcane DST magicks

Older releases (from the initial code on 2014-06-12 to 0.10.3 on 2015-04-18)

I’m not giving a changelog for these artefacts of ancient history. If you really care you can look through the Git history easily enough. Most of the releases were just compensating for changes to the language (that being before Rust 1.0; yes, this crate has been around for a while).

I do think that src/lib.rs in the first commit is a work of art, a thing of great beauty worth looking at; its simplicity is delightful, and it doesn’t even need to contain any unsafe code.
