Enum ChannelState 

pub enum ChannelState {
    Active,
    Quiesced {
        reason: String,
    },
}

The state machine’s two states, as a value.

Quiesced is terminal within a process lifetime: there is no un-quiesce and no removal, so the only exit is a restart, which drops the runtime roster entirely.

Variants

Active

New publishes and new subscribes are admitted.

Quiesced

New publishes and new subscribes are refused, carrying reason; subscribers that already hold a stream keep it.

Fields

reason: String

The operator-supplied cause, recorded once at the transition.
