Suggestion by @pgherveou.
Use
MaxEncodedLen::max_encoded_len()
instead of hardcoded sizes for allocating part of the buffer for the data of the return value of a host fn.This allows the types for
AccountId
andHash
to be properly configurable, currently they are restricted to a max size of those hardcoded values.
