Struct diesel_mysql_spatial::data_types::BoundingBox

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

An axis-aligned bounding rectangle.

MySQL doesn’t support native Rects. Corresponding functions like ST_Envelope() return a Polygon of the shape POLYGON((MINX MINY, MAXX MINY, MAXX MAXY, MINX MAXY, MINX MINY)) instead. This struct exists to provide more convenient access to the coordinates if your column always contains such polygons.

Warning: This can only be unserialized from a Polygon column. If polygons in other shapes are unserialized, the process may either fail or silently result in wrong bounds.

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

Fields

srid: SRID

geom: Rect<f64>

Methods from Deref<Target = Rect<f64>>

pub fn set_min<C>(&mut self, min: C) where
    C: Into<Coordinate<T>>, 

Set the Rect’s minimum coordinate.

Panics

Panics if min’s x/y is greater than the maximum coordinate’s x/y.

pub fn set_max<C>(&mut self, max: C) where
    C: Into<Coordinate<T>>, 

Set the Rect’s maximum coordinate.

Panics

Panics if max’s x/y is less than the minimum coordinate’s x/y.

pub fn to_lines(&self) -> [Line<T>; 4]

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

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

impl Clone for BoundingBox

fn clone(&self) -> BoundingBox

Returns a copy of the value.

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