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 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 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.
