Struct 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<Coord<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<Coord<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]

Trait Implementations

impl AsMut<Rect> for BoundingBox

fn as_mut(&mut self) -> &mut Rect<f64>

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

impl AsRef<Rect> for BoundingBox

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 duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundingBox

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

Formats the value using the given formatter.

impl Deref for BoundingBox

type Target = Rect

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for BoundingBox

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<BoundingBox> for Geometry

fn from(other: BoundingBox) -> Self

Converts to this type from the input type.

impl From<BoundingBox> for Polygon

fn from(other: BoundingBox) -> Self

Converts to this type from the input type.

impl From<Rect> for BoundingBox

fn from(geom: Rect<f64>) -> Self

Converts to this type from the input type.

impl FromSql<Polygon, Mysql> for BoundingBox

fn from_sql(bytes: Option<&[u8]>) -> Result<Self>

See the trait documentation.

impl<__ST, __DB> FromSqlRow<__ST, __DB> for BoundingBox

where __DB: Backend, Self: FromSql<__ST, __DB>,

fn build_from_row<R: Row<__DB>>(row: &mut R) -> Result<Self>

See the trait documentation.

const FIELDS_NEEDED: usize = 1usize

The number of fields that this type will consume. Must be equal to the number of times you would call row.take() in build_from_row

impl PartialEq for BoundingBox

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

impl<__ST, __DB> Queryable<__ST, __DB> for BoundingBox

where __DB: Backend, Self: FromSql<__ST, __DB>,

type Row = BoundingBox

The Rust type you’d like to map from.

fn build(row: Self::Row) -> Self

Construct an instance of this type

impl ToSql<Polygon, Mysql> for BoundingBox

fn to_sql<W: Write>(&self, out: &mut Output<'_, W, Mysql>) -> Result

See the trait documentation.
