Enum CoordType 

pub enum CoordType {
    Int8,
    UInt8,
    Int16,
    UInt16,
    Int32,
    UInt32,
    Float32,
    Float64,
}

An enum over the allowed coordinate types in the spatial index.

This can be used to infer the coordinate type from an existing buffer.

Implementations

impl CoordType

pub fn from_buffer<T: AsRef<[u8]>>(data: &T) -> Result<Self, GeoIndexError>

Infer the CoordType from an existing buffer.

This can be used to discern the generic type to use when constructing an RTreeRef or KDTreeRef.

use geo_index::rtree::RTreeBuilder;
use geo_index::rtree::sort::HilbertSort;
use geo_index::CoordType;

let mut builder = RTreeBuilder::<u32>::new(2);
builder.add(0, 0, 2, 2);
builder.add(1, 1, 3, 3);
let tree = builder.finish::<HilbertSort>();

let coord_type = CoordType::from_buffer(&tree).unwrap();
assert!(matches!(coord_type, CoordType::UInt32));

This method works for both buffers representing RTree or KDTree trees.

Trait Implementations

impl Clone for CoordType

fn clone(&self) -> CoordType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoordType

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

Formats the value using the given formatter.

impl Hash for CoordType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CoordType

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