Enum BroadcastReason 

pub enum BroadcastReason {
    PreciseUnavailable(SelectionError),
    PreciseDegradedUnusable {
        staleness: StalenessMetadata,
        error: SppError,
    },
}

Why solve_with_fallback produced a fix from broadcast ephemeris.

A broadcast fix is never substituted silently: the result records whether the precise selection was declined outright, or a stale-but-within-cap precise product was selected and then turned out unusable for the requested epoch.

Variants

PreciseUnavailable(SelectionError)

The precise product staleness selection declined: there was no precise product set, none covering or preceding the epoch, or the nearest product was beyond the staleness cap. The selection layer’s SelectionError is the exact reason.

PreciseDegradedUnusable

A stale (within-cap) precise product was selected, but it could not produce a fix for the requested epoch – typically its coverage does not reach the epoch (an SP3 nearest-prior product ends before it). This is the “precise unavailable for this epoch” condition the fallback exists for, so broadcast was used; the selected product’s staleness and the precise solve error are carried so the degraded-then-fell-back path is explicit. A solve failure on a product that DOES cover the epoch is a genuine error and is returned as FallbackError::Precise instead, not turned into this.

Fields

staleness: StalenessMetadata

Staleness of the degraded precise product that was tried.

error: SppError

The precise solve error that triggered the fallback.

Implementations

impl BroadcastReason

pub fn attempted_staleness(&self) -> Option<StalenessMetadata>

The precise selection’s staleness for the degraded-then-fell-back case, or None when the precise selection was declined outright. This is the staleness of the precise product that was not used; the broadcast fix itself carries no precise staleness.
