Struct ArrayVector 

pub struct ArrayVector<'a> { /* private fields */ }

A fixed-size list vector borrowed from a DataChunkHandle.

Exposes a fixed-width list whose child storage is contiguous across all rows.

Implementations

impl<'a> ArrayVector<'a>

pub fn logical_type(&self) -> LogicalTypeHandle

Get the logical type of this ArrayVector.

pub fn get_array_size(&self) -> u64

Returns the size of the array type.

pub fn row_is_null(&self, row: u64) -> bool

Returns true if the row at the given index is null.

Panics

Panics if row is outside the vector capacity.

pub fn try_row_is_null(&self, row: u64) -> Result<bool>

Returns whether the row is null, or an error if it is out of range.

pub fn child(&self, capacity: usize) -> FlatVector<'a>

Returns the child vector. capacity should be a multiple of the array size.

Panics

Panics if capacity is not a multiple of the fixed array size or exceeds the child allocation derived from the parent capacity.

pub unsafe fn set_child<T: Copy>(&self, data: &[T])

Set primitive data to the child node.

Panics

Panics if data.len() is not a multiple of the fixed array size.

Safety

The caller must ensure T matches the child vector’s physical storage and no other references to the same storage exist during the copy. The caller must also ensure the child backing allocation has space for all data elements; nested callers can arrange this by reserving capacity on the parent list vector before taking the array child.

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

Set row as null
