Subject: Make BlindedPayInfo fields public
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=f91879a5155a5c7482060414b2c0ed4ff5de0037;p=rust-lightning

Make BlindedPayInfo fields public

BlindedPayInfo fields need to be public in order to construct one for
fuzz tests. Typically, they would be constructed from ChannelUpdateInfo
for public channels and ChannelDetails for unannounced channels. For
now, make the fields public so they can be constructed manually.
