Struct PanelHandle 

pub struct PanelHandle { /* private fields */ }

A mounted panel’s resources and the router’s database, which a background job keeps to build a context per run without declaring the panel again. Cloning it is cheap.

let builder = Router::builder()
    .discover()
    .app_context(db)
    .panel(Panel::new("admin").resource::<PostResource>())?;
let admin = builder.panel_handle("admin").expect("mounted above");
let router = builder.build();

// In the job, once per run:
let cx = admin.context().with(Tenant(tenant));
let posts = scoped_query::<PostResource>(&cx)?;

Implementations

impl PanelHandle

pub fn context(&self) -> Cx

A context outside any request in which the panel’s resources answer as the panel mounted them, as Panel::context builds: it holds the database and the resources, and no request, session or tenant. Add a tenant with cx.with(Tenant(id)).

The context is one unit of work, as a request is: loads it memoizes stay cached for its lifetime, so a job builds one per run.
