Struct ColumnChunkData 

pub struct ColumnChunkData { /* private fields */ }

In-memory columnar buffer for fixed-size values.

Implementations

impl ColumnChunkData

pub fn new(data_type: LogicalType, capacity: u64) -> Self

Create a new column chunk for the given type and capacity.

pub fn data_type(&self) -> &LogicalType

pub fn capacity(&self) -> u64

pub fn num_values(&self) -> u64

pub fn is_null(&self, pos: u64) -> bool

pub fn set_null(&mut self, pos: u64, is_null: bool)

pub fn null_mask(&self) -> &NullMask

pub fn null_mask_mut(&mut self) -> &mut NullMask

pub fn stats(&self) -> &ColumnChunkStats

pub fn metadata(&self) -> &ColumnChunkMetadata

pub fn set_metadata(&mut self, metadata: ColumnChunkMetadata)

pub fn residency_state(&self) -> ResidencyState

pub fn set_residency_state(&mut self, state: ResidencyState)

pub fn get_value<T: FixedSizeValue>(&self, pos: u64) -> T

Get a typed value at the given position.

pub fn set_value<T: FixedSizeValue>(&mut self, pos: u64, val: T)

Set a typed value at the given position.

pub fn append_value<T: FixedSizeValue>(&mut self, val: T)

Append a typed value, incrementing num_values.

pub fn append_null(&mut self)

Append a null value, incrementing num_values.

pub fn get_raw(&self, pos: u64) -> &[u8]

Get raw bytes at a position.

pub fn set_raw(&mut self, pos: u64, bytes: &[u8])

Set raw bytes at a position.

pub fn scan_range<T: FixedSizeValue>( &self, start: u64, count: u64, ) -> Vec<Option<T>>

Scan a range of typed values, returning None for nulls.

pub fn buffer(&self) -> &[u8]

Get the byte buffer backing this chunk (read-only).

pub fn num_bytes_per_value(&self) -> usize

Number of bytes per value.

pub fn set_num_values(&mut self, n: u64)

Set num_values directly (used when bulk-loading).
