Modules

backend

IDB backend trait and supporting types for persistent IDB caching.

database

The Database abstraction: compiles a Mangle program, loads EDB facts, executes the program, and serves queries from the resulting store.

file_backend

File-based IDB backend: stores cached IDB snapshots as simplerow files.

file_source

File-based EDB source: reads .mgr (simplerow) and .mg (Mangle source) files.

provenance

Provenance tracking and the DRed (Delete/Re-derive) algorithm for incremental IDB maintenance.

simplerow

SimpleRow format: a row-oriented fact file format using Mangle syntax.

source

EDB source trait and supporting types.
