SessionOnMain

brep_render::runner

Enum SessionOnMain 

Source 
pub enum SessionOnMain {
    Resident,
    Copied(SessionTransfer),
    Unavailable,
}
Expand description

The history-run seam: SUBMIT a run, POLL for its completed reply, RESET the delta baseline, plus a QUERY channel for per-object measurements (routed to the runner so the warm registry answers them, never the cold main-side one). The Inline impl runs everything synchronously; a later thread/worker impl defers the work and surfaces the replies through the same poll idiom. Where the main thread gets the assembly session of the run it applied (HistoryRunner::session_for_main).

Variants§

§

Resident

The run executed on the main thread and its session is still the thread’s: nothing to do.

§

Copied(SessionTransfer)

An owned copy from the runner’s thread, to import.

§

Unavailable

Not available (busy, replaced, or a runner that cannot copy): replay.
