Struct FlatVector 

pub struct FlatVector { /* private fields */ }

Fixed-size values stored in a flat byte buffer with a separate null mask. For i64 columns: 8 bytes/value vs 32 bytes for TypedValue::Int64.

Implementations

impl FlatVector

pub fn from_column_chunk(c: &ColumnChunkData, num_rows: usize) -> Self

Construct from a ColumnChunkData by copying its byte buffer and NullMask.

pub fn from_raw( data: Vec<u8>, null_mask: NullMask, logical_type: LogicalType, num_values: usize, stride: usize, ) -> Self

Construct from raw components (used by JIT projection output).

pub fn get_value(&self, idx: usize) -> TypedValue

Extract a single TypedValue at a physical index.

pub fn is_null(&self, idx: usize) -> bool

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn null_mask(&self) -> &NullMask

Direct access to the null mask for batch evaluation.

pub fn logical_type(&self) -> &LogicalType

The logical type of values in this vector.

pub fn data_ptr(&self) -> *const u8

Raw pointer to the flat byte buffer (for JIT compiled code).

pub fn stride(&self) -> usize

Value stride in bytes.

pub fn data_as_i64_slice(&self) -> &[i64]

Reinterpret the flat byte buffer as a typed i64 slice. Caller must ensure logical_type is Int64 or Serial.

pub fn data_as_i32_slice(&self) -> &[i32]

Reinterpret the flat byte buffer as a typed i32 slice.

pub fn data_as_f64_slice(&self) -> &[f64]

Reinterpret the flat byte buffer as a typed f64 slice.

pub fn data_as_f32_slice(&self) -> &[f32]

Reinterpret the flat byte buffer as a typed f32 slice.

Trait Implementations

impl Clone for FlatVector

fn clone(&self) -> FlatVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlatVector

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

Formats the value using the given formatter.
