### Features
Feature defines what is the main codec used by `#[main_codec]`. However it is still possible to define them directly: `#[use_scale]`, `#[use_postcat]`, `#[no_codec]`.
```rust
default = ["scale"]
scale = ["reth-codecs-derive/scale"]
postcard = ["reth-codecs-derive/postcard"]
no_codec = ["reth-codecs-derive/no_codec"]
