Function encode 

pub fn encode(index: &ArtifactIndex) -> Result<Vec<u8>, IndexError>

Serialize index as JSON and zstd-compress it — the bytes the OCI layer carries.

Not compiled for wasm32: zstd does not build there and the edge never encodes indexes — producers (admin, CI) and the CLI consumer are all native.

Errors

IndexError::Serialize or IndexError::Compress.
