我在 Go 中有以下代码，我想用 Rust 重写：

func New(l *lexer.Lexer) *Parser {
    p := &Parser{l: l}
    // Read two tokens, so curToken and peekToken 
    // are both set
    p.nextToken()
    p.nextToken()
    return p
}
func (p *Parser) nextToken() {
    p.curToken = p.peekToken
    p.peekToken = p.l.NextToken()
}

在 Rust 中，我有如下内容：

struct Parser {
    l: lexer::Lexer,
    cur_token: lexer::Token,
    peek_token: lexer::Token,
}
impl Parser {
    fn new(l: lexer::Lexer, cur_token: lexer::Token, peek_token: lexer::Token) -> Self {
        Self {
            l: l,
            cur_token: cur_token,
            peek_token: peek_token,
        }
    }
    fn init(&mut self) {
        self.next_token();
        self.next_token();
    }
    fn next_token(&mut self) {
        self.cur_token = self.peek_token;
        self.peek_token = self.l.next_token();
    }
}

这是用 Rust 编写代码的最佳方式吗？
