Struct Chunk 

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

Implementations

impl<T> Chunk<T>

pub fn new(data: Arc<[T]>) -> Self

pub fn total_len(&self) -> usize

Returns the total length of the data chunk

pub fn len(&self) -> usize

Returns the number of visible elements in the data chunk

pub fn is_empty(&self) -> bool

Returns whether the chunk has zero visible elements.

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

Returns the element at the given index if the index is out of bounds, it returns None

Arguments

• index - The index of the element

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

Returns the visibility of the element at the given index if the index is out of bounds, it returns None

Arguments

• index - The index of the element

pub fn set_visibility(&mut self, visibility: Vec<bool>)

Sets the visibility of the elements in the data chunk. Note that the length of the visibility vector should be equal to the length of the data chunk.

Note that this is the only way to change the visibility of the elements in the data chunk, the data chunk does not provide a way to change the visibility of individual elements. This is to ensure that the visibility of the elements is always in sync with the data. If you want to change the visibility of individual elements, you should create a new data chunk.

Arguments

• visibility - A vector of boolean values indicating the visibility of the elements

pub fn iter(&self) -> DataChunkIteraror<'_, T>

Returns an iterator over the visible elements in the data chunk The iterator returns a tuple of the element and its index

Returns

An iterator over the visible elements in the data chunk
