Subject: Drop clone on tuple-field-fetching
X-Git-Tag: v0.0.110.2^2~3
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=096b386b1bb6d440d80de4ea528ccfb58305b9e4;p=ldk-java

Drop clone on tuple-field-fetching

Early in the lifetime of the bindings here tuple-field-fetching
had memory tracking issues which appear to have been solved now.
Thus, we can go ahead and drop the clone, at least for has-inner
types.

Fixes #84.
