Function buffer_with 

pub fn buffer_with<G>(
    geometry: &G,
    settings: BufferSettings,
) -> Result<MultiPolygon<Polygon<G::Point>>, OverlayError>
where
    G: Geometry,
    G::Kind: BufferStrategyForKind,
    <<G::Point as Point>::Cs as CoordinateSystem>::Family: DefaultBuffer<<<G::Point as Point>::Cs as CoordinateSystem>::Family>,
    <G::Kind as BufferStrategyForKind>::S: BufferStrategy<G, DefaultBufferStrategy<G>>,

Buffer a geometry with Boost’s complete distance/side/join/end/point strategy bundle.

Mirrors the five explicit strategy arguments to boost::geometry::buffer from algorithms/detail/buffer/interface.hpp:246-273.

Errors

Returns OverlayError::Unsupported for non-finite/inapplicable distance policies or degenerate linear input.
