Subject: Bound `Persister`'s `WriteableScore` by `Deref`
X-Git-Tag: v0.0.124-rc1~19^2
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=636125e089005bfd5c45bf47b8593c6fa1a1792a;p=rust-lightning

Bound `Persister`'s `WriteableScore` by `Deref`

This makes the trait marginally more flexible, but more importantly
matches our normal structure which makes the bindings generator a
bit happier.
