Installation

To use crustal clone the repository into the lib folder of your Rust project, or use crates.io

Usage

You can use crustal by adding the following lines to Cargo.toml file.

[dependencies]
crustal

Next, create a Scope and use the builder API to create elements in the scope. Lastly, call Scope::to_string() to get formatted C code as a string.

use crustal as CG;

let mut scope = CG::Scope::new();
scope.set_filename("include/my_file.hpp");

scope.push_doc_str("WARNING: This is auto-generated comment\n");
scope.new_include("stdio.h", true);

scope.new_class("MyClass")
        .set_base("StateBase", CG::Visibility::Public)
        .push_attribute(CG::Attribute::new(
        "name",
        CG::Type::new(CG::BaseType::new_int(8)),
    ));

println!("{}", scope.to_string());

produces the output

/// WARNING: This is auto-generated comment
#include <stdio.h>
class MyClass : public StateBase {

    private:
    uint64_t name;
}
