Crate bitemporal_runtime 

bitemporal-runtime

Bitemporal truth primitives for append-supersede temporal data.

Core concepts

• valid_time: When something is true in the domain (business time)
• recorded_time: When the system learned about it (system time)
• append-supersede: Updates never mutate; they append a new row and mark prior rows superseded

Key types

• BitemporalRecord<T>: A temporal record with valid_time, recorded_time, and value
• SupersessionReceipt: Cryptographic receipt for every supersession event

Functions

• append_supersede: Insert a new record, mark prior records superseded
• as_of_query: Query records valid at a specific valid_time as of a specific recorded_time
• temporal_snapshot: Retrieve full state as of a specific recorded_time
