pub fn minify_versions(
versions: &[Map<String, Value>],
) -> Vec<Map<String, Value>>Expand description
Minify a fully-materialized version list (newest-first) into the
composer/2.0 sparse-diff form. Inverse of expand_versions:
expand_versions(minify_versions(v)) == v for any well-formed v
(compared as key/value sets — key order is not preserved).
The first entry is emitted whole; each later entry carries only the
keys that changed versus the entry before it, plus an UNSET
sentinel for every key the previous entry had that this one drops.
