Subject: Drop `#[no_mangle]`/`extern` flag for internal-only method
X-Git-Tag: v0.0.117.0^2~7
X-Git-Url: http://git.bitcoin.ninja/index.cgi?p=ldk-c-bindings;a=commitdiff_plain;h=737b617b2db60132ef7c89713124460c60a3fcca

Drop `#[no_mangle]`/`extern` flag for internal-only method

This prevents new `cbindgen` from generating bindings for things we
don't actually want to export.
