Struct ColumnCacheReader

pub struct ColumnCacheReader { /* private fields */ }

Column Cache Reader Stores all data in a column format. Upon construction, all columns are decoded from the protobuf. This allows for quick and easy access to data in a column format.

Implementations

impl ColumnCacheReader

pub fn new() -> Self

create an instance

pub fn get_string(&mut self, index: usize) -> String

get a string

pub fn get_unsigned(&self, index: usize) -> u64

get an unsigned integer

pub fn get_signed(&self, index: usize) -> i64

get a signed integer

pub fn get_float(&self, index: usize) -> f32

get a float

pub fn get_double(&self, index: usize) -> f64

get a double

pub fn get_points(&mut self, index: usize) -> VectorPoints

get a vector of points used by all geometry types

pub fn get_points_3d(&mut self, index: usize) -> VectorPoints3D

get a vector of 3D points used by all geometry types

pub fn get_indices(&mut self, index: usize) -> Vec<u32>

get a vector of indices used by all geometry types

pub fn get_shapes(&mut self, index: usize) -> Vec<usize>

get a vector of encoded data that helps decode shapes

pub fn get_bbox(&mut self, index: usize) -> BBOX

get a BBox

Trait Implementations

impl Debug for ColumnCacheReader

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

Formats the value using the given formatter.

impl Default for ColumnCacheReader

fn default() -> ColumnCacheReader

Returns the “default value” for a type.

impl ProtoRead for ColumnCacheReader

fn read(&mut self, tag: u64, pb: &mut Protobuf)

The read method is used to read a field from a protobuf message. The tag parameter is used to determine which field to read into the struct. The pbf parameter is used to read the data in the appropriate format.
