newtype IntersectionNotFoundException Source #

Thrown when the user-provided custom point of intersection is unknown to the local node. This may happen if users shut down their node quickly after starting them and hold on a not-so-stable point of the chain. When they turn the node back on, that point may no longer exist on the network if a fork with deeper roots has been adopted in the meantime.
