+# TODOS
+* [ ] Implement all [data formats](https://serde.rs/#data-formats), or at least the one that expose a serde serializer or deserializer.
+  * [ ] BSON
+  * [ ] CBOR
+  * [ ] DBus (not sure it is working, but it compile…)
+  * [ ] Envy (deserialization only)
+  * [ ] Envy store (deserialization only)
+  * [ ] GVariant => See DBus: the same crate propose both
+  * [X] JSON
+  * [ ] JSON5
+    * [X] Deserialization
+    * [ ] Serialization
+  * [X] S-Expressions (lisp)
+  * [X] Pickle
+    * [ ] Test properly both way
+  * [ ] Query String (URL)
+    * [ ] Deserialization
+    * [X] Serialization
+  * [ ] MessagePack
+    * [ ] Deserialization
+    * [X] Serialization
+  * [X] RON
+  * [ ] TOML
+  * [X] YAML
+  * [ ] …
+* [ ] Add tests for each serializer and each deserializer (at least one)
+* [ ] Check if crates have features that we should enable/disable
+  * [ ] `zvariant` looks to include async runtime by default
+* [ ] Check my notes for each data format and open an issue on the crates to point problem/present my project and ask for help
+* [ ] Add proper error handling (find a mentor to explain me propper error management: struct, enum, … and then use anyhow/this_error if needed)
