+## 📶 Features
+
+Available library rust features:
+- `codec` - 💮 enable serialization and deserialization with `Serde`.
+  This is especially convenient in the process of forming AST, Codegen, 
+  a serialized representation of the `SemanticState`. Another important 
+  nuance is that any library that implements `Serde` can act as a 
+  serializer `codec`. For example formats: `json`, `toml`, `yaml`, 
+  `binary`, and many others that can use `serde` library.
+  The main entities, which apply the `codec` feature is:
+  - [x] `AST` ↪️ AST data source can be presented with serialized source.
+    This is especially useful for designing and testing `Codegen`, AST data 
+    transfer pipeline, and also for use as a data generation source for 
+    AST - any programming language that can generate serialized AST data.
+  - [x] `State` ↪️ `SematniсState` can be obtained in the form of 
+    serialized data. This is especially convenient for storing state 
+    before code generation with different parameters, post-analysis, 
+    optimizations - which will allow to work with already analyzed 
+    data.
+  - [x] `SemanticStack` ↪️ contains a set of instructions for `Codegen`. 
+    Representation in serialized form may be convenient for cases: code 
+    generation without repeated semantic analysis, only based on 
+    instructions for the code generator generated by the `semantic analyzer`. 
+    Serialized data represented `SemanticStack` - opens up wide 
+    possibilities for using any third-party code generators and compilers 
+    implemented in any programming language.
