Function subtract_2d 

pub fn subtract_2d(
    profile: &Profile2D,
    void_contour: &[Point2<f64>],
) -> Result<Profile2D>

Perform 2D boolean difference: profile - void_contour

Takes a profile and subtracts a void contour from it, returning a new profile with the void added as a hole (or modifying the outer boundary if the void cuts through it).

Arguments

• profile - The base profile to subtract from
• void_contour - The void footprint to subtract (any winding; normalised CCW)

Returns

• Ok(Profile2D) - The resulting profile with the void subtracted
• Err - If the operation fails
