按名称转换

基于字段/变体名称派生core::convert::From和core::convert::Into实现的程序宏。该Crate仅支持struct和enum。不支持union。

示例

#[derive(PartialEq, Debug)]
struct Point2D {
    x: i32,
    y: i32,
}

#[derive(PartialEq, Debug, ConvertByName)]
#[from(Point2D)]
#[into(Point2D)]
struct Vec2D {
    x: i32,
    y: i32,
}

let point = Point2D { x: 3, y: 4 };

let vector: Vec2D = point.into();
assert_eq!(vector, Vec2D { x: 3, y: 4 });

let point2: Point2D = vector.into();
assert_eq!(point2, Point2D { x: 3, y: 4 });
