Struct vadeen_osm::geo::Boundary

pub struct Boundary {
    pub min: Coordinate,
    pub max: Coordinate,
    pub freeze: bool,
}

Represents coordinate boundary, i.e. min and max latitude and longitude.

Examples

// Default creates boundaries cover the whole world
let bounds = Boundary::default();

assert_eq!(bounds.min.lat(), -90.0);
assert_eq!(bounds.min.lon(), -180.0);
assert_eq!(bounds.max.lat(), 90.0);
assert_eq!(bounds.max.lon(), 180.0);

// Inverted boundary is same as default, but with max as min and min as max.
// Useful when the boundary is intended to be dynamically expanded.
let mut bounds = Boundary::inverted();

assert_eq!(bounds.min.lat(), 90.0);
assert_eq!(bounds.min.lon(), 180.0);
assert_eq!(bounds.max.lat(), -90.0);
assert_eq!(bounds.max.lon(), -180.0);

bounds.expand((10.0, 20.0).into());
bounds.expand((30.0, 40.0).into());

assert_eq!(bounds.min.lat(), 10.0);
assert_eq!(bounds.min.lon(), 20.0);
assert_eq!(bounds.max.lat(), 30.0);
assert_eq!(bounds.max.lon(), 40.0);

Fields

min: Coordinate

max: Coordinate

freeze: bool

Methods

impl Boundary

pub fn inverted() -> Self

Same as default() but inverted so min contains max and max contains min. Used when a boundary are intended to be expanded by coordinates.

pub fn expand(&mut self, c: Coordinate)

Expand boundary if necessary to include a coordinate.

Trait Implementations

impl Clone for Boundary

fn clone(&self) -> Boundary

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Boundary

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

Formats the value using the given formatter.

impl Default for Boundary

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Boundary

impl PartialEq<Boundary> for Boundary

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

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

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

This method tests for !=.
