# Description We derive few useful traits on `ErrorOrigin` and `ExecError`, including `codec::Encode` and `codec::Decode`, so that `ExecResult` is en/decodable as well. This is required for a contract mocking feature (already prepared in drink: https://github.com/Cardinal-Cryptography/drink/pull/61). In more detail: `ExecResult` must be passed from runtime extension, through runtime interface, back to the pallet, which requires that it is serializable to bytes in some form (or implements some rare, auxiliary traits). **Impact on runtime size**: Since most of these traits is used directly in the pallet now, compiler should be able to throw it out (and thus we bring no new overhead). However, they are very useful in secondary tools like drink or other testing libraries. # Checklist - [x] My PR includes a detailed description as outlined in the "Description" section above - [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process) of this project (at minimum one label for `T` required) - [x] I have made corresponding changes to the documentation (if applicable) - [x] I have added tests that prove my fix is effective or that my feature works (if applicable)

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
