dump ron file in rust

To dump a RON (Rusty Object Notation) file in Rust, you can use the ron::ser::to_writer function. This function serializes a Rust object to RON and writes the result to a writer. Here is an example:

main.rs
use std::fs::File;
use std::io::BufWriter;
use ron::ser::to_writer;

// Define your Rust object
struct MyStruct {
    field1: i32,
    field2: String,
}

// Create an instance of your object
let my_object = MyStruct { field1: 42, field2: String::from("hello") };

// Open a file to write to
let file = File::create("my_file.ron").unwrap();
let writer = BufWriter::new(file);

// Serialize your Rust object to RON and write it to the file
to_writer(writer, &my_object).unwrap();

In this example, we define a Rust struct called MyStruct and create an instance of it. We then create a file to write to using the File::create function and wrap the file in a BufWriter. Finally, we call to_writer with the BufWriter and a reference to the instance of MyStruct to serialize it to RON and write it to the file.

Note that you'll need to add the ron crate as a dependency in your Cargo.toml file to use the RON serialization functions.
