Struct TupleEncoder 

pub struct TupleEncoder { /* private fields */ }

Encodes rows into Binary Tuples according to a fixed schema.

Reusable: create once per schema, encode many rows. Internal buffers are reused across calls to minimize allocation.

Implementations

impl TupleEncoder

pub fn new(schema: &StrictSchema) -> Self

Create an encoder for the given schema.

pub fn encode(&self, values: &[Value]) -> Result<Vec<u8>, StrictError>

Encode a row of values into a Binary Tuple.

values must have exactly schema.len() entries. A Value::Null is allowed only if the corresponding column is nullable.

pub fn schema(&self) -> &StrictSchema

Access the schema this encoder was built for.

pub fn encode_bitemporal( &self, system_from_ms: i64, valid_from_ms: i64, valid_until_ms: i64, user_values: &[Value], ) -> Result<Vec<u8>, StrictError>

Encode a row for a bitemporal strict schema. The three reserved slots (0/1/2) are populated from the provided timestamps; the remaining slots are filled from user_values in schema order.

Errors if the schema is not bitemporal or if user_values.len() != schema.len() - 3.
