Struct diesel_mysql_spatial::data_types::MultiLineString

pub struct MultiLineString {
    pub srid: SRID,
    pub geom: MultiLineString<f64>,
}

A collection of LineStrings.

MySQL extension: The spatial reference system identifier (SRID) may identify the used coordinate system.

Fields

srid: SRID

geom: MultiLineString<f64>

Methods from Deref<Target = MultiLineString<f64>>

pub fn is_closed(&self) -> bool

True if the MultiLineString is empty or if all of its LineStrings are closed - see LineString::is_closed.

Examples

use geo_types::{MultiLineString, LineString, line_string};

let open_line_string: LineString<f32> = line_string![(x: 0., y: 0.), (x: 5., y: 0.)];
assert!(!MultiLineString::new(vec![open_line_string.clone()]).is_closed());

let closed_line_string: LineString<f32> = line_string![(x: 0., y: 0.), (x: 5., y: 0.), (x: 0., y: 0.)];
assert!(MultiLineString::new(vec![closed_line_string.clone()]).is_closed());

// MultiLineString is not closed if *any* of it's LineStrings are not closed
assert!(!MultiLineString::new(vec![open_line_string, closed_line_string]).is_closed());

// An empty MultiLineString is closed
assert!(MultiLineString::<f32>::new(vec![]).is_closed());

fn as_ref(&self) -> &MultiLineString<f64>

Converts this type into a shared reference of the (usually inferred) input type.

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

impl Deref for MultiLineString

type Target = MultiLineString<f64>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
