如何在rust中使用nom解析对称的带引号的字符串？

[dependencies]
nom = "6.2.1"

use nom::{
    character::complete::{char, multispace0},
    sequence::delimited,
    IResult,
};

#[derive(Debug)]
struct QuotedString {
    value: String,
}

fn quoted_string(input: &str) -> IResult<&str, QuotedString> {
    let (input, _) = multispace0(input)?;
    let (input, _) = char('"')(input)?;
    let (input, value) = delimited(char('"'), nom::character::complete::escaped(nom::character::complete::none_of("\""), '\\', char('\"')), char('"'))(input)?;
    let (input, _) = multispace0(input)?;
    
    Ok((input, QuotedString { value: value.to_string() }))
}

fn main() {
    let input = r#""Hello, World!""#;
    let result = quoted_string(input);
    
    match result {
        Ok((_, parsed)) => println!("Parsed string: {:?}", parsed),
        Err(e) => println!("Parsing error: {:?}", e),
    }
}

Parsed string: QuotedString { value: "Hello, World!" }
