Module tarantool::tuple

Tuples

The tuple submodule provides read-only access for the tuple userdata type. It allows, for a single tuple: selective retrieval of the field contents, retrieval of information about size, iteration over all the fields, and conversion from/to rust structures

• KeyDef
  An object which describes how to extract a key for a given tarantool index from a tuple. Basically it contains information the parts of the key, specifically location of the parts within the tuple, their types, their nullability and collation.

Traits

• Decode
  Decode Types implementing this trait can be decoded from msgpack.
• DecodeOwned
  Types implementing this trait can be decoded from msgpack by value.
• Encode
  Encode Types implementing this trait can be serialized into a valid tarantool tuple (msgpack array).
• ToTupleBuffer
  ToTupleBuffer Types implementing this trait can be converted to tarantool tuple (msgpack array).
• TupleIndex
  TupleIndex Types implementing this trait can be used as arguments for the Tuple::get method.

Functions

• session_push
  Push MessagePack data into a session data channel - socket, console or whatever is behind the session. Note, that successful push does not guarantee delivery in case it was sent into the network. Just like with write()/send() system calls.
