Struct KernelExactPoint2 

Source 
pub struct KernelExactPoint2 {
    pub x_num: i128,
    pub y_num: i128,
    pub den: i128,
}
Expand description

Optional exact-construction capabilities. A kernel MAY implement this trait in addition to GeometryKernel; algorithms that need exact construction require K: GeometryKernel + ConstructionKernel at compile time.

P10.4: Methods return Result<T, Unsupported> — a typed error, not a panic. A kernel that does not support a construction returns Err(Unsupported::new(...)), and the caller can degrade gracefully.

Fields§

§x_num: i128

Numerator of the x-coordinate (exact integer).

§y_num: i128

Numerator of the y-coordinate (exact integer).

§den: i128

Common denominator (always positive).
