Crate fastxdr

To generate Rust types from an XDR spec at build time, add fastxdr to your Cargo.toml:

[build-dependencies]
# For the code generation
fastxdr = "1.0"

[dependencies]
# Required dependencies of the generated code
thiserror = "1.0"
bytes = "0.5"

And add a build.rs at the crate root (not in src!):

fn main() {
    // Tell Cargo to regenerate the types if the XDR spec changes
    println!("cargo:rerun-if-changed=xdr_spec.x");

    // Read from xdr_spec.x, writing the generated code to out.rs
    std::fs::write(
        std::path::Path::new(std::env::var("OUT_DIR").unwrap().as_str()).join("out.rs"),
        fastxdr::Generator::default()
            .generate(include_str!("xdr_spec.x"))
            .unwrap(),
    )
    .unwrap();
}

And then include the generated file in your application:

// Where out.rs is the filename from above
include!(concat!(env!("OUT_DIR"), "/out.rs"));
use xdr::*;

To view the generated types, either export the generated types in your application and use cargo doc, or use the CLI to produce the generated code directly for reading.
