Struct h3o::geom::MultiLineString

pub struct MultiLineString(/* private fields */);

A collection of geo::LineString.

Note that the ToCells implementation suffers from the same limitation that grid_path_cells, which means that on error max_cells_count returns 0 and to_cells an empty iterator.

Implementations

impl MultiLineString

pub fn from_radians( lines: MultiLineString<f64> ) -> Result<Self, InvalidGeometry>

Initialize a collection of lines from lines whose coordinates are in radians.

Errors

InvalidGeometry if one of the line is invalid (e.g. contains non-finite coordinates).

Example

use geo::line_string;
use h3o::geom::MultiLineString;

let line_string: geo::LineString<f64> = line_string![
    (x: 1.996408325715777, y: 0.534292570530397),
    (x: 2.208424012168513, y: 0.7995167582816788),
    (x: 2.1213562369319434, y: 0.5449632604075227),
];
let lines = geo::MultiLineString::new(vec![line_string]);
let lines = MultiLineString::from_radians(lines)?;

pub fn from_degrees( lines: MultiLineString<f64> ) -> Result<Self, InvalidGeometry>

Initialize a collection of lines from lines whose coordinates are in degrees.

Errors

InvalidGeometry if one of the line is invalid (e.g. contains non-finite coordinates).

Example

use geo::line_string;
use h3o::geom::MultiLineString;

let line_string: geo::LineString<f64> = line_string![
    (x: 114.385771248293,   y: 30.612709316587612),
    (x: 126.53337527260373, y: 45.8089358995214),
    (x: 121.54475921995464, y: 31.22409481103989),
];
let lines = geo::MultiLineString::new(vec![line_string]);
let lines = MultiLineString::from_degrees(lines)?;

Trait Implementations

impl Clone for MultiLineString

fn clone(&self) -> MultiLineString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MultiLineString

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

Formats the value using the given formatter.

impl From<MultiLineString> for MultiLineString<f64>

fn from(value: MultiLineString) -> Self

Converts to this type from the input type.

impl PartialEq for MultiLineString

fn eq(&self, other: &MultiLineString) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToCells for MultiLineString

fn max_cells_count(&self, config: PolyfillConfig) -> usize

Returns an upper bound to the number of cells returned by to_cells.

fn to_cells( &self, config: PolyfillConfig ) -> Box<dyn Iterator<Item = CellIndex> + '_>

Computes the coverage of the input using cell indexes of the specified resolution.
