Enum CoordBuffer

pub enum CoordBuffer<const D: usize> {
    Interleaved(InterleavedCoordBuffer<D>),
    Separated(SeparatedCoordBuffer<D>),
}

An Arrow representation of an array of coordinates.

As defined in the GeoArrow spec, coordinates can either be interleaved (i.e. a single array of XYXYXY) or separated (i.e. two arrays, one XXX and another YYY).

This CoordBuffer abstracts over an InterleavedCoordBuffer and a SeparatedCoordBuffer.

For now all coordinate buffers support only two dimensions.

This is named CoordBuffer instead of CoordArray because the buffer does not store its own validity bitmask. Rather the geometry arrays that build on top of this maintain their own validity masks.

Variants

Interleaved(InterleavedCoordBuffer<D>)

Separated(SeparatedCoordBuffer<D>)

Trait Implementations

impl<const D: usize> Clone for CoordBuffer<D>

fn clone(&self) -> CoordBuffer<D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const D: usize> Debug for CoordBuffer<D>

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

Formats the value using the given formatter.

impl<const D: usize> From<CoordBufferBuilder<D>> for CoordBuffer<D>

fn from(value: CoordBufferBuilder<D>) -> Self

Converts to this type from the input type.

impl<const D: usize> From<InterleavedCoordBuffer<D>> for CoordBuffer<D>

fn from(value: InterleavedCoordBuffer<D>) -> Self

Converts to this type from the input type.

impl<const D: usize> From<SeparatedCoordBuffer<D>> for CoordBuffer<D>

fn from(value: SeparatedCoordBuffer<D>) -> Self

Converts to this type from the input type.

impl<const D: usize> IntoArrow for CoordBuffer<D>

type ArrowArray = Arc<dyn Array>

The type of arrow array that this geoarrow array can be converted into.

fn into_arrow(self) -> Self::ArrowArray

Converts this geoarrow array into an arrow array.

impl<const D: usize> PartialEq for CoordBuffer<D>

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

type Error = GeoArrowError

The type returned in the event of a conversion error.

fn try_from(value: &dyn Array) -> Result<Self, Self::Error>

Performs the conversion.

impl<const D: usize> TryFrom<CoordBuffer<D>> for CoordSeq

Available on crate feature geos only.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: CoordBuffer<D>) -> Result<Self, Error>

Performs the conversion.
