global-cache-schema.sql raw

-- Cargo's cache-tracking schema, as cargo itself creates it in
-- `$CARGO_HOME/.global-cache`.
--
-- This is not grunk's schema to define; it is reproduced here so that tests can
-- build a cargo home without running cargo. Keeping it in one file means the
-- unit tests and the end-to-end tests agree about what they are testing
-- against, and that there is a single place to look when cargo's schema moves.
