tl

TL

TL is a data description language and data storage format.

Implementation details

We do not rush go version until we need some new feature or (more often) we need a fix from our dependency, which requires newer go version.

Overview

In general, interest in TL stems from a desire to serialize data and make RPC calls to servers that implement TL RPC, as well as to implement such servers

TL describes data structures, including RPC queriesand their responses, using syntax derived from functional programming languages.

The TL format is characterized by compactness and high efficiency.

TL is schema-driven format. Tool caled tlgen is used to generate structs/classes and (de)serialization methods.
