Struct VblankRate 

struct VblankRate {
    captures: Vec<Arc<Controls>>,
    published: u32,
    conn: Option<(RustConnection, Window, Atom, Atom)>,
}

The rate the X server’s fake vblank runs at while this process captures it: the fastest live capture’s frame rate, published on the root window as _FAKE_SCREEN_MILLIHZ (CARDINAL, millihertz, 1000 to 1000000) and, rounded to whole frames for servers that read only that, _FAKE_SCREEN_FPS (1 to 1000), both deleted when the last capture ends. The Selkies Xvfb paces the clients that wait on Present by it, keeping the rate it started at as a floor unless the published one is at most 0.1% slower (59.94 under 60), so a vsynced application presents as fast as it is streamed; any other server holds it as inert data.

Fields

captures: Vec<Arc<Controls>>

published: u32

Millihertz last published, 0 for none.

conn: Option<(RustConnection, Window, Atom, Atom)>

The connection, the root window, and the millihertz and frames-per-second atoms.
