Metadata V15: Expose API to fetch metadata for version #13287

lexnv · 2023-01-31T17:26:12Z

This PR extends the Metadata API to fetch the metadata at a given provided version.

It lays the foundation for keeping the metadata V14 around and exposing the V15 for early adopters before making a major breaking change.

The runtime API comes with 2 new functions:

metadata_at_version - Fetch the metadata at a given version
metadata_versions - List the supported versions by metadata_at_version

At the current moment, substrate only supports V14.
Soon, the V15 will be exposed as unstable under the u32::max value.

Users could then fetch the v15 metadata, allowing for an appropriate time to migrate their use cases.

Part of: #12939.

Suggested change

/// Returns the supported versions of metadata.

/// This can be used to call `metadata_at_version`.

/// Returns the available metadata versions.

Nit; Just because "This can be used to call.." felt a bit unclear :)

I would keep "supported". Feels more clear on what this is about.

I'm not an expert in this area but it looks good to me!

Looks good, but we should forward the selection of the supported metadata to the metadata crate. See my comments for more information.
