§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:
ⓘ
[dependencies]
capnp = "0.21" # Note this is a different library than capnp*c*
[build-dependencies]
capnpc = "0.21"
In your build.rs:
ⓘ
fn main() {
capnpc::CompilerCommand::new()
.src_prefix("schema")
.file("schema/foo.capnp")
.file("schema/bar.capnp")
.run().expect("schema compiler command");
}
In your lib.rs:
ⓘ
capnp::generated_code!(mod foo_capnp);
capnp::generated_code!(mod bar_capnp);
This will be equivalent to executing the shell command
ⓘ
capnp compile -orust:$OUT_DIR --src-prefix=schema schema/foo.capnp schema/bar.capnp
