How do I write a literal quotation mark when using the formatting macros?
-1
I need to create a JSON file with some simple data, but the Rust compiler doesn't recognize " " as symbols in file.write_all(b" !HERE! ");. These are necessary in JSON syntax. I tried r#""# but it also doesn't work.
use std::fs::File;
use std::io::prelude::*;
fn main() {
let mut file = File::create("model.json").expect("fail creating file");
file.write_all(b"!HERE!").expect("fail writing data");
}
Is there a solution for this issue?

An empty string slice, aka""is totaly legit.let a = "";will work! However, if you try to do something likelet a = """"it will not work in any language I know of. You have to escape the inner quotations withlet a = """";

I think your original approach is correct:
let mut file = File::create("model.json").expect("fail creating file");
let json = r#"{"key1": "value1", "key2": "value2"}"#;
file.write_all(json.as_bytes()).expect("fail writing data");
