For access to length(), normalise(), // or angle() however, you must be using either Vector2D or // Vector2D. For types with an Add and Mul implementation, the functions dot() and // length_squared() are available. // Casts between signed and unsigned primitives will perform bounds // checking, so casting the vector (-10.0, 2.0) to a Vector2D will // result in the vector (0, 2). #Length of a vector 2d full#The full list of interoperable primitives is as follows: // - i32, i64, isize // - u32, u64, usize // - f32, f64 // As primitives generally implement From/Into for lossless casts, // an as_Ts() function is not available for those types, and // from(.)/into() should be favoured. In // this case you can use specialised functions, as shown below: assert_eq !( Vector2D:: new( 13, 11), v2. If there is no From or Into implementation, then you're out of luck // unless you are using specific primitives, such as i32 and f64. // If the target type has a implementation of From, then you // can either use source.into_vec2d() or Vector2D::from_vec2d(source). There are two ways to cast between Vector2Ds, depending on the source // and target types. Alternatively you can use new(.) to condense instantiation let v2: Vector2D = Vector2D:: new( 13.0, 11.5) Vectors have fields X and Y, these can be of any type let v1: Vector2D = Vector2D
