Crate capnpc

Cap'n Proto Schema Compiler Plugin Library

This library allows you to do Cap'n Proto code generation within a Cargo build. You still need the capnp binary (implemented in C++). (If you use a package manager, try looking for a package called capnproto.)

In your Cargo.toml:

[package]
build = "build.rs"

[build-dependencies]
capnpc = "0.8"

In your build.rs:

extern crate capnpc;

fn main() {
    capnpc::CompilerCommand::new()
        .src_prefix("schema")
        .file("schema/foo.capnp")
        .file("schema/bar.capnp")
        .run().expect("schema compiler command");
}

This will be equivalent to executing the shell command

capnp compile -orust:$OUT_DIR --src-prefix=schema schema/foo.capnp schema/bar.capnp

Modules
