This provides something similar to what `RwLock<Arc<T>>` is or what
`Atomic<Arc<T>>` would be if it existed, optimized for read-mostly write-seldom

Read [the documentation](https://docs.rs/arc-swap) before using.

## Rust version policy

The 1. version will build on any edition 2018 capable compiler. This does not
include:

* Tests. Tests build and run on recent compilers, mostly because of
  dependencies.
* Additional feature flags. Most feature flags are guaranteed to build since the
  version they are introduced. Experimental features are without any guarantees.
