Struct SeparatedCoordBuffer

pub struct SeparatedCoordBuffer { /* private fields */ }

An array of coordinates stored in separate buffers of the same length.

This stores all coordinates in separated fashion as multiple underlying buffers: e.g. xxx and yyy for 2D coordinates.

Implementations

impl SeparatedCoordBuffer

pub const COORD_TYPE: CoordType = CoordType::Separated

The underlying coordinate type

pub fn from_array( buffers: [ScalarBuffer<f64>; 4], dim: Dimension, ) -> GeoArrowResult<Self>

Construct a new SeparatedCoordBuffer from an array of existing buffers.

The number of valid buffers in the array must match the dimension size. E.g. if the dim is Dimension::XY, then only the first two buffers must have non-zero length, and the last two buffers in the array can have length zero.

pub fn from_vec( buffers: Vec<ScalarBuffer<f64>>, dim: Dimension, ) -> GeoArrowResult<Self>

Construct a new SeparatedCoordBuffer from a Vec of existing buffers.

All buffers within buffers must have the same length, and the length of buffers must equal the dimension size.

pub fn raw_buffers(&self) -> &[ScalarBuffer<f64>; 4]

Access the underlying coordinate buffers.

Note that not all four buffers may be valid. Only so many buffers have defined meaning as there are dimensions, so for an XY buffer, only the first two buffers have defined meaning, and the last two may be any buffer, or empty.

pub fn buffers(&self) -> Vec<ScalarBuffer<f64>>

Access the underlying coordinate buffers.

In comparison to raw_buffers, all of the returned buffers are valid.

pub fn dim(&self) -> Dimension

The dimension of this coordinate buffer

pub fn len(&self) -> usize

The number of coordinates

pub fn is_empty(&self) -> bool

Whether the coordinate buffer is empty

pub fn from_coords<'a>( coords: impl ExactSizeIterator<Item = &'a (impl CoordTrait<T = f64> + 'a)>, dim: Dimension, ) -> GeoArrowResult<Self>

Construct from an iterator of coordinates

Trait Implementations

impl Clone for SeparatedCoordBuffer

fn clone(&self) -> SeparatedCoordBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SeparatedCoordBuffer

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

Formats the value using the given formatter.

impl From<SeparatedCoordBuffer> for CoordBuffer

fn from(value: SeparatedCoordBuffer) -> Self

Converts to this type from the input type.

impl From<SeparatedCoordBuffer> for StructArray

fn from(value: SeparatedCoordBuffer) -> Self

Converts to this type from the input type.

impl PartialEq for SeparatedCoordBuffer

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