I've been closely watching for someone to start making ledger-cli bindings for Rust. I investigated doing it myself and reasoned that it would be a very large undertaking that would likely involve significant changes to the C++ code to accommodate the port. Most of the work would be around implementing a C-only interface to much of ledger-cli, then writing the bindings in Rust. This would probably be several dozen hours of work.
Frankly, it would seem "easier" to start ledger-cli in console mode as a background process. The Rust program would then feed it commands on its STDIN and parse the output on STDOUT. ledger-cli has an xml output mode but that's mostly for dumping resolved transaction data. You could probably make the output more parseable using the --display-format option crafted to output something that serde can parse easily (JSON, most likely). The quest for a good GUI for reporting led me to Scala-based Abandon initially, but I've since switched to ledger-cli + ledger2beancount + fava.
