Enum DeclaredWhen 

pub enum DeclaredWhen {
    Always,
    PhaseField(&'static str),
    AdapterActive(&'static str),
    Driver(&'static str),
}

The condition under which a control is actually declared on the component tree — the why isn’t this knob here? a user needs when a control is absent from a given run.

Variants

Always

Declared on every activity, unconditionally.

PhaseField(&'static str)

Declared when a phase/op sets the named field (e.g. rate ⇒ the rate: phase field both seeds and declares the rate control).

AdapterActive(&'static str)

Declared when the named adapter is active in the run.

Driver(&'static str)

Declared only when the named driver implementation backs its adapter (e.g. cassandra-cpp for the cql adapter — the pure-Rust scylla driver does not declare it). Adapter-owned but driver-specific.
