Enum Arm 

pub(crate) enum Arm {
    Idle,
    Subscribe,
    More,
    Refresh,
}

The workload an arm sends, as a closed set.

A closed set rather than a string, so a mistyped arm is refused rather than run as something else. An arm that ran a different workload under the name a person typed is the defect this instrument exists to find, and it is the same mistake whether the code or the caller makes it.

Variants

Idle

Nothing at all, and the baseline every other arm is charged against.

Subscribe

One connect and one subscribe: the price of arriving.

More

An attach, then --asks pages.

Refresh

An attach, then --asks subscribe-reloads, each an unsubscribe and a subscribe - what the client sends on every update for the open seat.
