Struct salsa::Revision [−][src]
pub struct Revision { /* fields omitted */ }
Expand description
A unique identifier for the current version of the database; each
time an input is changed, the revision number is incremented.
Revision
is used internally to track which values may need to be
recomputed, but is not something you should have to interact with
directly as a user of salsa.
