Implementations

impl PointBuffer

pub fn with_capacity(dtype: DType, capacity: usize) -> Self

Creates an empty buffer for the given dtype.

pub fn from_f32(values: Vec<f32>) -> Self

Creates a buffer from an existing f32 vector.

pub fn len(&self) -> usize

Returns the number of elements in the buffer.

pub fn is_empty(&self) -> bool

Returns whether the buffer is empty.

pub fn dtype(&self) -> DType

Returns the buffer dtype.

pub fn resize(&mut self, len: usize, field: &PointField) -> SpatialResult<()>

Resizes the buffer to the requested number of elements.

pub fn as_f32(&self) -> SpatialResult<&[f32]>

Returns immutable access to an f32 column.

pub fn as_f32_mut(&mut self) -> SpatialResult<&mut Vec<f32>>

Returns mutable access to an f32 column.

pub fn push_f32(&mut self, value: f32) -> SpatialResult<()>

Appends one f32 value.

pub fn push_f64(&mut self, value: f64) -> SpatialResult<()>

Appends one f64 value.

pub fn push_u8(&mut self, value: u8) -> SpatialResult<()>

Appends one u8 value.

pub fn push_u16(&mut self, value: u16) -> SpatialResult<()>

Appends one u16 value.

pub fn push_i32(&mut self, value: i32) -> SpatialResult<()>

Appends one i32 value.

Trait Implementations

impl Clone for PointBuffer

fn clone(&self) -> PointBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointBuffer

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

Formats the value using the given formatter.

impl PartialEq for PointBuffer

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