Expand description

ToTupleBuffer Types implementing this trait can be converted to tarantool tuple (msgpack array).

Required Methods§

source

fn write_tuple_data(&self, w: &mut impl Write) -> Result<()>

Provided Methods§

source

fn to_tuple_buffer(&self) -> Result<TupleBuffer>

source

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

Returns a slice of bytes represeting the underlying tarantool tuple.

Returns None if Self doesn’t contain the data, in which case the ToTupleBuffer::to_tuple_buffer should be used.

This method exists as an optimization for wrapper types to eliminate extra copies, in cases where the implementing type already contains the tuple data (e.g. TupleBuffer, RawBytes, etc.).

Object Safety§

This trait is not object safe.
