---

function distance

double QfSnappingResult::distance () const

for vertex / edge match units depending on what class returns it (geom.cache: layer units, map canvas snapper: dest crs units)

---

function edgePoints

Only for a valid edge match - obtain endpoints of the edge.

void QfSnappingResult::edgePoints (
    QgsPoint & pt1,
    QgsPoint & pt2
) const

---

function featureId

QgsFeatureId QfSnappingResult::featureId () const
