* Adds support for interating with Streams over interfaces that are tagged
with the x-dropshot-pagination extension. This requires clients to use
the futures crate.
Adds tests that compile generated clients.
Updates nexus.json to reflect a more recent omicron API.
Changes all generated methods to have a lifetime ('a) bound on all
references. This isn't necessary for most methods, but greatly
simplifies generation of the associated paginated interface.
introduce an intermediate form; this is going to be used to generate a few different things:
- an interator interface for paginated APIs; the IR will let us re-use
the typify types
- a CLI generator that will generate calls into the generated client
- an automated test harness that will validate the generated client
against a mock server
