* "A path is considered invalid if and only if it enters and exits an address node through trust lines where No Ripple has been enabled for that address." (https://xrpl.org/rippling.html#specifics) * When loading trust lines for an account "Alice" which was reached via a trust line that has the No Ripple flag set on Alice's side, do not use or cache any of Alice's trust lines which have the No Ripple flag set on Alice's side. For typical "end-user" accounts, this will return no trust lines.
