help

Hello everyone,

I need to convert a structure to JSON; the idea is not to use external crates, just what the language provides. What can I use?

fn convert_vector_in_json() {
let format = format!(
"[
id:{id}
]",
id = 10
);
println!("{:?}", format.to_string())
}

Code i use

Why are you trying not to use an existing crate?

The project is CLI-based and I'm using rustc; I don't know how to add a crate.

Here's an example of how you could do it but, as the author of the response says, you would be better off using cargo instead.

Thank you very much; your answers were very helpful.

You can look at a simple JSON parser I wrote several months ago. Although it is wrapped in a crate, it has 0 dependencies and can be just inserted in your codebase.

How is the fact that your project is CLI-based relevant to the question?
