Struct MultiPartShapeM 

pub struct MultiPartShapeM {
    pub base: MultiPartShape,
    pub m_range: (f64, f64),
    pub m_values: Vec<f64>,
}

A multi-part shape with M (measure) values (PolyLineM, PolygonM, or MultiPointM)

Binary layout (after shape type):

• Box2D (32 bytes: x_min, y_min, x_max, y_max)
• num_parts (4 bytes)
• num_points (4 bytes)
• parts array (num_parts * 4 bytes)
• points array (num_points * 16 bytes: x, y pairs)
• m_range (16 bytes: m_min, m_max)
• m_values array (num_points * 8 bytes)

Fields

base: MultiPartShape

Base 2D shape data (bbox, parts, points)

m_range: (f64, f64)

M value range (min, max)

m_values: Vec<f64>

M values for each point

Implementations

impl MultiPartShapeM

pub fn new( parts: Vec<i32>, points: Vec<Point>, m_values: Vec<f64>, ) -> Result<Self>

Creates a new multi-part shape with M values

pub fn read<R: Read>(reader: &mut R) -> Result<Self>

Reads a multi-part shape with M from a reader

pub fn write<W: Write>(&self, writer: &mut W) -> Result<()>

Writes a multi-part shape with M to a writer

pub fn content_length_words(&self) -> i32

Returns the content length in 16-bit words (excluding shape type)

Trait Implementations

impl Clone for MultiPartShapeM

fn clone(&self) -> MultiPartShapeM

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MultiPartShapeM

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

Formats the value using the given formatter.

impl PartialEq for MultiPartShapeM

fn eq(&self, other: &MultiPartShapeM) -> 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.
