Struct GeometryCollection

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

A collection of Geometry types.

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

Fields

srid: SRID

geom: GeometryCollection<f64>

Implementations

impl GeometryCollection

pub const fn empty(srid: SRID) -> Self

Construct an empty geometry collection

Methods from Deref<Target = GeometryCollection<f64>>

pub fn len(&self) -> usize

Number of geometries in this GeometryCollection

pub fn is_empty(&self) -> bool

Is this GeometryCollection empty

pub fn iter(&'a self) -> IterHelper<'a, T>

pub fn iter_mut(&'a mut self) -> IterMutHelper<'a, T>

Trait Implementations

impl AsMut<GeometryCollection> for GeometryCollection

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

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

impl AsRef<GeometryCollection> for GeometryCollection

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

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

impl Clone for GeometryCollection

fn clone(&self) -> GeometryCollection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeometryCollection

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

Formats the value using the given formatter.

impl Default for GeometryCollection

fn default() -> Self

Returns the “default value” for a type.

impl Deref for GeometryCollection

type Target = GeometryCollection

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for GeometryCollection

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

Mutably dereferences the value.

impl From<GeometryCollection> for Geometry

fn from(other: GeometryCollection) -> Self

Converts to this type from the input type.

impl From<GeometryCollection> for GeometryCollection

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

Converts to this type from the input type.

impl FromSql<GeometryCollection, Mysql> for GeometryCollection

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

See the trait documentation.

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

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 GeometryCollection

fn eq(&self, other: &GeometryCollection) -> 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 GeometryCollection

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

type Row = GeometryCollection

The Rust type you’d like to map from.

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

Construct an instance of this type

impl ToSql<Geometry, Mysql> for GeometryCollection

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

See the trait documentation.

impl ToSql<GeometryCollection, Mysql> for GeometryCollection

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

See the trait documentation.

impl TryFrom<Geometry> for GeometryCollection

type Error = <GeometryCollection as TryFrom<Geometry>>::Error

The type returned in the event of a conversion error.

fn try_from(other: Geometry) -> Result<Self, Self::Error>

Performs the conversion.
