Enum RecoveryEstimate 

pub enum RecoveryEstimate {
    Immediate,
    NotRecoverable,
    UnknownStateSize {
        hint: &'static str,
    },
    Hydrate {
        state_mb: u32,
        seconds: f64,
        basis: String,
    },
}

How long it takes to get the state back, and on what basis that is claimed.

Every non-trivial variant here is an extrapolation from two measured constants (MEASURED_HYDRATE_MB_PER_S, MEASURED_GET_RTT_MS) applied to a declared state size. Nothing in this module has ever timed a real restore. That is stated on the type rather than in a footnote because a recovery-time number without its provenance is the single easiest thing in a planning report to mistake for a measurement.

Variants

Immediate

Nothing to hydrate — the workload carries no durable state.

NotRecoverable

There is no copy to recover from. Recovery is not a duration.

UnknownStateSize

A copy exists but the spec does not say how big the state is, so the transfer cannot be estimated. Names the annotation that would fix it.

Fields

hint: &'static str

Hydrate

Bulk transfer of a declared state size at the measured throughput.

Fields

state_mb: u32

seconds: f64

basis: String

Verbatim provenance, carried into JSON so a consumer cannot strip it.
