Struct LongArrayColumn 

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

LONG_ARRAY column: per-row n-D shape and flat little-endian i64 elements.

Implementations

impl<'a> LongArrayColumn<'a>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn validity(&self) -> Validity<'a>

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

pub fn shape(&self, row: usize) -> Option<&'a [u32]>

pub fn raw(&self, row: usize) -> Option<&'a [u8]>

pub fn element_count(&self, row: usize) -> usize

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

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

Concatenated little-endian i64 element bytes for every row, addressed per row by data_offsets.

pub fn data_offsets(&self) -> &'a [u32]

Per-row byte offsets into data; len() + 1 entries, row r spanning [data_offsets[r], data_offsets[r + 1]).

pub fn shapes(&self) -> &'a [u32]

Concatenated per-row shapes (dimension lengths), addressed per row by shape_offsets.

pub fn shape_offsets(&self) -> &'a [u32]

Per-row offsets into shapes; len() + 1 entries.
