我正在使用 cratetoml = "0.5.8"来解析 TOML 文件。我的预期输出应该存储在这个结构中：

#[derive(Deserialize, Debug)]
pub struct Config {
    pub watching: Vec<Stocks>,
}

#[derive(Deserialize, Debug)]
pub struct Stocks {
    pub symbol: String,
}

这是我解析 TOML 文件的函数：

pub fn parse_toml_file(path: String) -> Config {
    let content = fs::read_to_string(path).expect("Failed to access file.");

    let toml_config: Config = toml::from_str(&content[..]).expect("Failed to parse file.");

    toml_config
}

这就是我所说的：

let home: String = format!("{:?}", home_dir().unwrap());
let path: String = format!(
    "{}/.config/stonks.toml",
    home[1..home.len() - 1].to_string()
);
let cli = Cli::new(parse_toml_file(path));

这是content变量的值：

"[watching]\nsymbol = [\"AAPL\", \"TSLA\"]\n"

这是我在创建toml_config变量时遇到的错误：

thread 'main' panicked at 'Failed to parse file.: Error { inner: ErrorInner { kind: Custom, line: Some(0), col: 0, at: Some(0), message: "invalid type: map, expected a sequence", key: ["watching"] } }', src/parse.rs:19:60
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

如何修复此错误？内容按预期打印出来。
