Struct ArrayParts

pub struct ArrayParts { /* private fields */ }

ArrayParts represents a parsed but not-yet-decoded deserialized Array. It contains all the information from the serialized form, without anything extra. i.e. it is missing a DType and len, and the encoding_id is not yet resolved to a concrete vtable.

An ArrayParts can be fully decoded into an ArrayRef using the decode function.

Implementations

impl ArrayParts

pub fn decode( &self, ctx: &ArrayContext, dtype: DType, len: usize, ) -> VortexResult<ArrayRef>

Decode an ArrayParts into an ArrayRef.

pub fn encoding_id(&self) -> u16

Returns the array encoding.

pub fn metadata(&self) -> Option<&[u8]>

Returns the array metadata bytes.

pub fn nchildren(&self) -> usize

Returns the number of children.

pub fn child(&self, idx: usize) -> ArrayParts

Returns the nth child of the array.

pub fn nbuffers(&self) -> usize

Returns the number of buffers.

pub fn buffer(&self, idx: usize) -> VortexResult<ByteBuffer>

Returns the nth buffer of the current array.
