Struct FixedLineString 

pub struct FixedLineString<const N: usize> { /* private fields */ }

A fixed-capacity polyline (open line string) backed by an inline array.

Stores up to N Point2D vertices with no heap allocation.

Implementations

impl<const N: usize> FixedLineString<N>

pub fn new() -> Self

Creates an empty FixedLineString.

pub fn push(&mut self, p: Point2D) -> Result<(), NoAllocError>

Attempts to append a point. Returns Ok(()) on success or Err(NoAllocError::CapacityExceeded) if full.

pub fn len(&self) -> usize

Returns the number of points in the line string.

pub fn is_empty(&self) -> bool

Returns true if the line string contains no points.

pub fn get(&self, index: usize) -> Option<&Point2D>

Returns the point at the given index, or None if out of bounds.

pub fn as_slice(&self) -> &[Point2D]

Returns a slice of the current points.

pub fn total_length(&self) -> f64

Computes the total length of the polyline (sum of segment lengths).

Returns 0.0 for line strings with fewer than 2 points.

pub fn bbox(&self) -> Option<BBox2D>

Returns the axis-aligned bounding box, or None if empty.

pub fn iter(&self) -> Iter<'_, Point2D>

Returns an iterator over the points.

pub const fn capacity(&self) -> usize

Returns the capacity of this line string.

pub fn clear(&mut self)

Clears all points, resetting the length to zero.

pub fn first(&self) -> Option<&Point2D>

Returns the first point, or None if empty.

pub fn last(&self) -> Option<&Point2D>

Returns the last point, or None if empty.

impl<const N: usize> Default for FixedLineString<N>

fn default() -> Self

Returns the “default value” for a type.
