Implementations

impl ColumnChunk

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

Create the appropriate column chunk for a logical type.

pub fn data_type(&self) -> &LogicalType

pub fn num_values(&self) -> u64

pub fn capacity(&self) -> u64

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

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

pub fn append_null(&mut self)

pub fn residency_state(&self) -> ResidencyState

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

Set raw bytes at a position. Only valid for Fixed chunks.

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

Set num_values directly (used when bulk-loading).
