Function sew_around_within 

pub fn sew_around_within(
    model: &mut Model,
    faces: &[Shape],
    settled: &[bool],
    gap: f64,
    tol: Tolerances,
) -> OgeomResult<Sewn>

Sew faces of which some are settled, as sew_around, across a gap of up to gap as sew_within sews: the edge kept, and the vertices it ends on, widen to reach the edge they replace.

Errors

As sew_around, and OgeomError::Construction if gap is not finite and non-negative.
