Cap'n Proto Language Bindings

Community-maintained language bindings implement Cap'n Proto serialization and, in many cases, the full RPC protocol. Serialization plus RPC is supported in C++, C#, Erlang, Go, Haskell, JavaScript (Node.js), OCaml, Python, and Rust. Serialization-only bindings exist for C, D, Java, Lua, Nim, Ruby, and Scala.
