Struct FixedReferenceChain 

#[non_exhaustive]
pub struct FixedReferenceChain { /* private fields */ }

A chain checked for a fixed-reference sweep; only fixed_reference_plan makes one, so a chain in hand has passed its checks.

Implementations

impl FixedReferenceChain

pub fn pieces(&self) -> &[PathPiece]

The pieces, in the direction of travel.

pub const fn reference(&self) -> Vec3

The unit reference direction.

pub const fn closed(&self) -> bool

Whether the last piece joins the first as a loop (see fixed_reference_plan).

pub const fn chord(&self) -> Scalar

The chord budget of the walls.

pub const fn reach(&self) -> Scalar

The profile’s furthest ring vertex from its origin.

pub const fn walls(&self) -> Scalar

The proven distance of the walls from the exact surface: zero for exactly one segment, else half the chord budget, of which the arcs’ largest twist term (Self::twist) is paid first and the spans get the rest.

pub const fn twist(&self) -> Scalar

The largest distance a profile vertex moves between the exact frame and the rotation-minimising stations on any arc (see the module notes); within an eighth of the chord budget.
