This crate allows to easily configure different codecs for different purposes (benchmarks, user configuration) with minimal changes. Having them to be configurable through annotations allows us to contain their implementations/leakage to isolated portions of the project.

Example:

Header struct

DB usage

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].

default = ["scale"]
scale = ["codecs-derive/scale"]
postcard = ["codecs-derive/postcard"]
no_codec = ["codecs-derive/no_codec"]
