方法已被定义。

错误示例

struct Point {
  x: Int
  y: Int
}

fn Point::to_string(self : Point) -> String {
  "(" + self.x.to_string() + "," + self.y.to_string() + ")"
}

fn Point::to_string(self : Point) -> String {
  "<" + self.x.to_string() + "," + self.y.to_string() + ">"
}

建议

请删除重复的方法，只保留一个：

struct Point {
  x: Int
  y: Int
}

fn Point::to_string(self : Point) -> String {
  "(" + self.x.to_string() + "," + self.y.to_string() + ")"
}

// Remove the second Point::to_string method
