Sui GraphQL client

This is a first version of Aftermath's Sui GraphQL client using [cynic].

The main item here is the GraphQlClient trait, defining the common interface for clients interacting with an RPC. See the reqwest feature for a pre-made implementation.

The queries inclued here (under feature queries) were constructed with the help of cynics generator and use the scalars defined in [sui_gql_schema].

Users building their own queries should first import [sui_gql_schema::schema] and register its schema. Read more about it in https://cynic-rs.dev/large-apis. You can check this crate's [build-dependencies] and build.rs for an example of how to do so.

It is recommended to use the generator with Sui's GraphQL schema and to try reusing the scalars defined in [sui_gql_schema] as those automatically convert opaque types to more useful ones like [af_sui_types].

Features

• move-types: compatibility with af-move-type types
• mutations: enables the mutations submodule
• queries: enables the queries submodule with pre-made queries
• reqwest: enables the reqwest submodule with an implementation of GraphQlClient
• scalars: re-exports the scalars module of [sui_gql_schema]

Handy links:

• Query builder: generator.cynic-rs.dev. When prompted either
  • click the "A URL" button and pass in:
    • https://sui-testnet.mystenlabs.com/graphql to build queries against the testnet schema
    • https://sui-mainnet.mystenlabs.com/graphql for the mainnet one
  • click the "I'll Paste It" button and paste the schema
