Struct ValueVector 

pub struct ValueVector { /* private fields */ }

A columnar vector of values.

ValueVector stores data in columnar format for efficient SIMD processing and cache utilization during query execution.

Implementations

impl ValueVector

pub fn new() -> Self

Creates a new empty generic vector.

pub fn with_type(data_type: LogicalType) -> Self

Creates a new empty vector with the given type.

pub fn from_values(values: &[Value]) -> Self

Creates a vector from a slice of values.

pub fn with_capacity(data_type: LogicalType, capacity: usize) -> Self

Creates a new vector with the given capacity.

pub fn data_type(&self) -> &LogicalType

Returns the data type of this vector.

pub fn len(&self) -> usize

Returns the number of entries in this vector.

pub fn is_empty(&self) -> bool

Returns true if this vector is empty.

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

Returns true if the value at index is null.

pub fn set_null(&mut self, index: usize)

Sets the value at index to null.

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

Pushes a boolean value.

pub fn push_int64(&mut self, value: i64)

Pushes an integer value.

pub fn push_float64(&mut self, value: f64)

Pushes a float value.

pub fn push_string(&mut self, value: impl Into<Arc<str>>)

Pushes a string value.

pub fn push_node_id(&mut self, value: NodeId)

Pushes a node ID.

pub fn push_edge_id(&mut self, value: EdgeId)

Pushes an edge ID.

pub fn push_value(&mut self, value: Value)

Pushes a generic value.

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

Gets a boolean value at index.

pub fn get_int64(&self, index: usize) -> Option<i64>

Gets an integer value at index.

pub fn get_float64(&self, index: usize) -> Option<f64>

Gets a float value at index.

pub fn get_string(&self, index: usize) -> Option<&str>

Gets a string value at index.

pub fn get_node_id(&self, index: usize) -> Option<NodeId>

Gets a node ID at index.

pub fn get_edge_id(&self, index: usize) -> Option<EdgeId>

Gets an edge ID at index.

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

Gets a value at index as a generic Value.

pub fn get(&self, index: usize) -> Option<Value>

Alias for get_value.

pub fn push(&mut self, value: Value)

Alias for push_value.

pub fn as_bool_slice(&self) -> Option<&[bool]>

Returns a slice of the underlying boolean data.

pub fn as_int64_slice(&self) -> Option<&[i64]>

Returns a slice of the underlying integer data.

pub fn as_float64_slice(&self) -> Option<&[f64]>

Returns a slice of the underlying float data.

pub fn as_node_id_slice(&self) -> Option<&[NodeId]>

Returns a slice of the underlying node ID data.

pub fn as_edge_id_slice(&self) -> Option<&[EdgeId]>

Returns a slice of the underlying edge ID data.

pub fn logical_type(&self) -> LogicalType

Returns the logical type of this vector.

pub fn copy_row_to(&self, row: usize, dest: &mut ValueVector)

Copies a row from this vector to the destination vector.

The destination vector should have a compatible type. The value at row is read from this vector and pushed to the destination vector.

pub fn clear(&mut self)

Clears all data from this vector.
