Required Methods

fn children(&self) -> Vec<ArrayRef>

Returns the children of the array.

fn nchildren(&self) -> usize

Returns the number of children of the array.

fn nth_child(&self, idx: usize) -> Option<ArrayRef>

Returns the nth child of the array without allocating a Vec.

Returns None if the index is out of bounds.

fn children_names(&self) -> Vec<String>

Returns the names of the children of the array.

fn named_children(&self) -> Vec<(String, ArrayRef)>

Returns the array’s children with their names.

fn buffers(&self) -> Vec<ByteBuffer>

Returns the buffers of the array.

fn buffer_handles(&self) -> Vec<BufferHandle>

Returns the buffer handles of the array.

fn buffer_names(&self) -> Vec<String>

Returns the names of the buffers of the array.

fn named_buffers(&self) -> Vec<(String, BufferHandle)>

Returns the array’s buffers with their names.

fn nbuffers(&self) -> usize

Returns the number of buffers of the array.

fn metadata(&self) -> VortexResult<Option<Vec<u8>>>

Returns the serialized metadata of the array, or None if the array does not support serialization.

fn metadata_fmt(&self, f: &mut Formatter<'_>) -> Result

Formats a human-readable metadata description.

fn is_host(&self) -> bool

Checks if all buffers in the array tree are host-resident.

This will fail if any buffers of self or child arrays are GPU-resident.
