duration

Overview ¶

Package duration parses the duration shape docsync writes in directives and in configuration: an integer followed by a unit.

It lives here, below both, because two callers need the same grammar and neither should import the other for it: the directive verbs read `expires=` and `review_every=`, and `[check] snapshot_max_age` reads the same shape. A config package that had to import the checker to validate one key would pull the whole evaluation tree behind a leaf.
