Json.createFlavor RestJson
|
|
|
|
## The RestJson format implements JSON serialization in the way specified
|
|
## by the Beacon API:
|
|
##
|
|
## https://ethereum.github.io/beacon-APIs/
|
|
##
|
|
## In this format, we must always set `allowUnknownFields = true` in the
|
|
## decode calls in order to conform the following spec:
|
|
##
|
|
## All JSON responses return the requested data under a data key in the top
|
|
## level of their response. Additional metadata may or may not be present
|
|
## in other keys at the top level of the response, dependent on the endpoint.
|
|
## The rules that require an increase in version number are as follows:
|
|
##
|
|
## - no field that is listed in an endpoint shall be removed without an increase
|
|
## in the version number
|
|
##
|
|
## - no field that is listed in an endpoint shall be altered in terms of format
|
|
## (e.g. from a string to an array) without an increase in the version number
|
|
##
|
|
## Note that it is possible for a field to be added to an endpoint's data or
|
|
## metadata without an increase in the version number.
|
|
##
|
|
## TODO nim-json-serializations should allow setting up this policy per format
|
|
##
|
|
## This also means that when new fields are introduced to the object definitions
|
|
## below, one must use the `Option[T]` type.
