The type is not a record type.

This error occurs when you try to construct a type that is not a struct using the T::{ .. } syntax.

错误示例

enum Point {
  D2(Double, Double)
  D3(Double, Double, Double)
}

fn main {
  let a = Point::{ x : 1.0, y : 2.0 }
  //      ^~~~~
  // Error: The type Point is not a record type
}

建议

You should use the correct syntax to construct the type.

fn main {
  let a = Point::D2(1.0, 2.0)
}
