Struct AdapterRegistration 

pub struct AdapterRegistration {
    pub names: fn() -> &'static [&'static str],
    pub known_params: fn() -> &'static [&'static str],
    pub display_preference: fn(&HashMap<String, String>) -> DisplayPreference,
    pub supported_controls: fn() -> &'static [ControlDesc],
    pub create: fn(HashMap<String, String>) -> CreateAdapterFuture,
}

An adapter module’s registration, submitted at link time via inventory.

Each adapter crate (nmbrs-adapter-stdout, nmbrs-adapter-cql, etc.) submits one of these. The shared runner collects all submissions to build the adapter dispatch table without any explicit adapter list.

Fields

names: fn() -> &'static [&'static str]

Driver names this adapter responds to (e.g., &["stdout"] or &["cql", "cassandra"]).

known_params: fn() -> &'static [&'static str]

Extra param names this adapter accepts (for CLI validation).

display_preference: fn(&HashMap<String, String>) -> DisplayPreference

Display preference for TUI activation. Checked at startup before any adapter is constructed — no connection overhead. Takes the run params so an adapter whose terminal use depends on config can decide (e.g. stdout wants the TUI off when it writes op output to the console, but is TUI-compatible when filename= redirects to a file).

supported_controls: fn() -> &'static [ControlDesc]

SRD-23 — the dynamic controls this adapter can declare, as static ControlDesc capability descriptors. This is the discovery surface (nmbrs describe controls / describe adapter=<name>), read without constructing the adapter; the adapter’s declare_controls derives the live control from the same descriptors so the two cannot drift. Default || &[] for adapters with no dynamic knobs.

create: fn(HashMap<String, String>) -> CreateAdapterFuture

Async factory: given params, create the adapter. Returns a boxed future so async connect is supported (e.g., CQL).
