Subject: Handle the somewhat half-mapped alias TransactionOutputs
X-Git-Tag: v0.0.98~2^2~5
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=aa1fab79e70b10280271c77a01626c62a18e46c4;p=ldk-java

Handle the somewhat half-mapped alias TransactionOutputs

TransactionOutputs is actually a
C2Tuple_TxidCVec_C2Tuple_u32TxOutZZZ, but with a type alias that
gives it a more readable name in a few places. Sadly, we don't
support type aliases, so we have to just map it back before building
our bindings.
