Subject: Mark `IndexedMap` types as `(C-not exported)`
X-Git-Tag: v0.0.114~12^2~1
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=08cb01e6ef9f6bfe0251c167acb89d7051c5da59;p=rust-lightning

Mark `IndexedMap` types as `(C-not exported)`

While we could try to expose the type explicitly, we already have
alternative accessors for bindings, and mapping `Hash`, `Ord` and
the other requirements for `IndexedMap` would be a good chunk of
additional work.
