Enum SpatialFilter 

pub enum SpatialFilter {
    CoversGeographyPoint {
        column: &'static str,
        lng: f64,
        lat: f64,
    },
    DWithinGeographyPoint {
        column: &'static str,
        lng: f64,
        lat: f64,
        radius_meters: f64,
    },
}

PostGIS spatial filter primitives. v1 ships two ops that cover the “is point inside this zone” / “is this point within radius of that zone” cases — the rest of the ST_* surface can land on demand.

All current variants treat the column as geography(Point, 4326) — the WGS-84 lat/lon CRS that PostGIS ships with extensions enabled. Casting happens at render time via ::geography so schemas storing geometry or geometry(...) columns work without extra annotations, at the cost of an in-flight cast each call.

Variants

CoversGeographyPoint

ST_Covers(col::geography, ST_MakePoint($lng, $lat)::geography). Matches when the column’s geography fully covers (contains including the boundary) the given point. Use for “is this caller-supplied point inside the row’s service area” lookups.

Fields

column: &'static str

lng: f64

lat: f64

DWithinGeographyPoint

ST_DWithin(col::geography, ST_MakePoint($lng, $lat)::geography, $radius_meters). Matches when the column’s geography is within radius_meters of the given point (great-circle distance on WGS-84, since ::geography triggers the spheroid path).

Fields

column: &'static str

lng: f64

lat: f64

radius_meters: f64

Trait Implementations

impl Clone for SpatialFilter

fn clone(&self) -> SpatialFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpatialFilter

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

Formats the value using the given formatter.

impl PartialEq for SpatialFilter

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