Struct gdnative_visual_script::common::geom::euclid::Length

#[repr(C)]
pub struct Length<T, Unit>(pub T, _);

A one-dimensional distance, with value represented by T and unit of measurement Unit.

T can be any numeric type, for example a primitive type like u64 or f32.

Unit is not used in the representation of a Length value. It is used only at compile time to ensure that a Length stored with one unit is converted explicitly before being used in an expression that requires a different unit. It may be a type without values, such as an empty enum.

You can multiply a Length by a scale::TypedScale to convert it from one unit to another. See the TypedScale docs for an example.
