LegacyValueVector

Struct LegacyValueVector 

Source
pub struct LegacyValueVector { /* private fields */ }
Expand description

A vector of values of the same physical type. This is the fundamental columnar data unit in Akar’s query execution.

Implementations§

Source§

impl LegacyValueVector

Source

pub fn new(physical_type: PhysicalTypeID, capacity: usize) -> Self

Source

pub fn physical_type(&self) -> PhysicalTypeID

Source

pub fn size(&self) -> usize

Source

pub fn capacity(&self) -> usize

Source

Source

pub fn set_null(&mut self, idx: usize, is_null: bool)

Source

pub fn resize(&mut self, new_size: usize)

Source

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

Get a reference to the raw data buffer.

Source

pub fn data_mut(&mut self) -> &mut [u8]

Source§

impl LegacyValueVector

Source

pub fn get_i64(&self, idx: usize) -> Option<i64>

Get an i64 value at index.

Source

pub fn set_i64(&mut self, idx: usize, val: i64)

Set an i64 value at index.

Source

pub fn get_i32(&self, idx: usize) -> Option<i32>

Get an i32 value at index.

Source

pub fn set_i32(&mut self, idx: usize, val: i32)

Set an i32 value at index.

Source

pub fn get_double(&self, idx: usize) -> Option<f64>

Get an f64 (double) value at index.

Source

pub fn set_double(&mut self, idx: usize, val: f64)

Set an f64 (double) value at index.

Source§

impl LegacyValueVector

Source

pub fn get_value(&self, idx: usize) -> Option<Value>

Get a Value enum from this vector at a given row index. This converts the raw byte buffer into the appropriate Value variant.

Source

pub fn set_value(&mut self, idx: usize, val: &Value) -> Result<(), String>

Set a Value at the given row index.

Converts the Value variant to the vector’s physical type. Returns an error if the type cannot be converted.

Source

pub fn push_bool(&mut self, val: bool)

Push a boolean value to the end of the vector.

Source

pub fn get_bool(&self, idx: usize) -> Option<bool>

Get a boolean value at index.

Source

pub fn push_string(&mut self, val: &str) -> Result<(), String>

Push a string value (stores as inline bytes for now). Returns an error if the string exceeds the 255-byte inline storage limit.

Source

pub fn append(&mut self, other: &LegacyValueVector)

Append a value from another vector (for DataChunk operations).
