Struct OrderedRowSerde

pub struct OrderedRowSerde {
    schema: Vec<DataType>,
    order_types: Vec<OrderType>,
}

OrderedRowSerde is responsible for serializing and deserializing Ordered Row.

Fields

schema: Vec<DataType>

order_types: Vec<OrderType>

Implementations

impl OrderedRowSerde

pub fn new(schema: Vec<DataType>, order_types: Vec<OrderType>) -> Self

pub fn prefix(&self, len: usize) -> Cow<'_, Self>

FIXME: This leads to allocation in most cases. Should allow using slices for the schema and order types.

pub fn index(&self, idx: usize) -> Cow<'_, Self>

pub fn serialize(&self, row: impl Row, append_to: impl BufMut)

Note: prefer Row::memcmp_serialize if possible.

pub fn serialize_datums( &self, datum_refs: impl Iterator<Item = impl ToDatumRef>, append_to: impl BufMut, )

Note: prefer Row::memcmp_serialize if possible.

pub fn deserialize(&self, data: &[u8]) -> Result<OwnedRow>

pub fn get_order_types(&self) -> &[OrderType]

pub fn get_data_types(&self) -> &[DataType]

pub fn deserialize_prefix_len( &self, key: &[u8], prefix_len: usize, ) -> Result<usize>

Trait Implementations

impl Clone for OrderedRowSerde

fn clone(&self) -> OrderedRowSerde

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
