Struct StationSeam 

#[non_exhaustive]
pub struct StationSeam {
    pub distance: f64,
    pub parameter: f64,
    pub smooth: bool,
    pub exact: bool,
}

A place inside a curve where two of its pieces meet; see the module documentation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

distance: f64

Distance from the curve’s start in its station measure: plan distance on an elevated or banked curve, arc length otherwise.

parameter: f64

The curve’s own parameter there: the vertex index of a polyline, the knot of a B-spline, the distance itself on every family whose parameter is its measure.

smooth: bool

Whether the stored data guarantees one section frame on both sides (a chain join, an intrinsic law’s seam). false means the frame MAY jump: evaluate both sides to see whether it does.

exact: bool

Whether distance is read from stored data alone (sums of stored lengths and of segment lengths); false for a quadrature.

Implementations

impl StationSeam

pub const fn new( distance: f64, parameter: f64, smooth: bool, exact: bool, ) -> StationSeam

A seam at distance (the station measure) and parameter (the curve’s own), smooth when the stored data guarantees one frame on both sides and exact when distance needs no quadrature.
