Provided Methods§

Source

fn register_schema_atomic<'life0, 'life1, 'async_trait>( &'life0 self, schema: Schema, subject: &'life1 Subject, ) -> Pin<Box<dyn Future<Output = SchemaResult<(SchemaId, SchemaVersion)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Atomically register a schema under a subject in a single write.

Combines ID allocation, schema storage, and subject-version registration into one durable write to prevent partial state from crashes between separate writes. Default implementation allocates an ID via next_schema_id, then stores the schema and registers the version (suitable for in-memory backends where atomicity is guaranteed).
