Struct ChunkedVec 

pub struct ChunkedVec<T> { /* private fields */ }

Column storage split into independently clone-on-write chunks.

Implementations

impl<T: Clone> ChunkedVec<T>

pub fn new() -> Self

Construct an empty column.

pub fn with_capacity(capacity: usize) -> Self

Construct an empty column with enough chunk slots for capacity.

pub fn len(&self) -> usize

Number of entries in the column.

pub fn is_empty(&self) -> bool

Return true when the column contains no entries.

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

Return the value at index, if it exists.

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

Append value to the column in amortized O(1) time.

Pushes go into the tail buffer through Arc::make_mut: while the tail Arc is unique this is a plain Vec::push; the first push after a clone pays one tail clone (≤ CHUNK_SIZE - 1 elements) and subsequent pushes reuse the now-unique buffer. When the tail reaches CHUNK_SIZE it freezes into an Arc<[T]> immediately and a fresh tail starts on the next push. Cloning the column shares frozen chunks and the tail via Arc refcount bumps — no element is copied at clone time.

pub fn set(&mut self, index: usize, value: T)

Replace the value at index.

Panics

Panics if index is out of bounds.

pub fn iter(&self) -> impl Iterator<Item = &T>

Iterate all values in insertion order.
