Trait SchemaRegistry 

pub trait SchemaRegistry: Send + Sync {
    // Required methods
    fn get_by_fingerprint(&self, fp: &EventFingerprint) -> Option<Schema>;
    fn get_by_name(&self, name: &str, version: Option<u32>) -> Option<Schema>;

}

A thread-safe, read-only view of a schema registry. Concrete implementations live in chaincodec-registry.
