Struct BorrowedCurve 

pub struct BorrowedCurve<'bufs> { /* private fields */ }

A curve with borrowed lists of path points and segment lengths.

Implementations

impl<'bufs> BorrowedCurve<'bufs>

pub fn new( mode: GameMode, points: &[PathControlPoint], expected_len: Option<f64>, bufs: &'bufs mut CurveBuffers, ) -> Self

Create a new BorrowedCurve which borrows from CurveBuffers.

pub const fn path(&self) -> &[Pos]

Path points of the BorrowedCurve.

pub const fn lengths(&self) -> &[f64]

The BorrowedCurve’s length at each path point.

pub fn position_at(&self, progress: f64) -> Pos

The interpolated position at the given progress.

pub fn progress_to_dist(&self, progress: f64) -> f64

Value between 0.0 and the curve’s distance, depending on the given progress between 0.0 and 1.0.

pub fn dist(&self) -> f64

The total distance of the BorrowedCurve.

pub fn idx_of_dist(&self, d: f64) -> usize

The index into BorrowedCurve::lengths to reach the distance d.

pub fn interpolate_vertices(&self, i: usize, d: f64) -> Pos

Interpolate the position between the i’th and i+1’th path position at distance d.

pub fn to_owned_curve(&self) -> Curve

Allocates the borrowed lists to transform BorrowedCurve into Curve.

Trait Implementations

impl<'bufs> Clone for BorrowedCurve<'bufs>

fn clone(&self) -> BorrowedCurve<'bufs>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'bufs> Debug for BorrowedCurve<'bufs>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'bufs> PartialEq for BorrowedCurve<'bufs>

fn eq(&self, other: &BorrowedCurve<'bufs>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
