pub async fn dispatch(app: App) -> Result<(), Box<dyn Error + Send + Sync>>Expand description
Parse argv and run the requested management subcommand against the
passed-in App. The user binary’s main.rs calls this after
building its App — see the module-level docs for the pattern.
The App must already be built (App::builder()...build()?) — the
builder phases publish the ambient pool and model registry, which
every management command reads. Passing a built App instead of
an AppBuilder keeps the boot order in the user’s hands and lets
them register plugins / models / databases freely before
dispatching.
