How to choose an adapter
Every adapter wraps a different wire transport but exposes the same
scenario.run() API. Pick by use case, then click through to the adapter page
for the constructor, capabilities, gotchas, and a worked example.
If you want to compare specifics side-by-side, see the capability matrix.
