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
|
||
|
|
scenarios, with consistent performance characteristics.

## 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.
