Struct VersionTracker 

pub struct VersionTracker { /* private fields */ }

Token-version tracker for json paths

Implementations

impl VersionTracker

pub fn new() -> Self

pub fn get(&self, path: &str) -> u64

pub fn bump(&mut self, path: &str)

pub fn merge_from(&mut self, other: &VersionTracker)

Merge version counters from other, taking the maximum for each path. Using max (not insert) ensures that if this tracker already saw a higher version for a path (e.g., from a previous subform evaluation round), it is never downgraded.

pub fn merge_from_params(&mut self, other: &VersionTracker)

Merge only /$params-prefixed version counters from other (max strategy). Used when giving a per-item tracker the latest schema-level param versions without absorbing data-path bumps that belong to other items.

pub fn any_bumped_with_prefix(&self, prefix: &str) -> bool

Returns true if any tracked path with the given prefix has been bumped (version > 0). Used to gate table re-evaluation when item fields change without the item being new.

pub fn any_newly_bumped_with_prefix( &self, prefix: &str, baseline: &VersionTracker, ) -> bool

Returns true if any path with the given prefix has a higher version than in baseline. Unlike any_bumped_with_prefix, this detects only brand-new bumps from a specific diff pass, ignoring historical bumps that were already present in the baseline.

pub fn versions(&self) -> impl Iterator<Item = (&str, &u64)>

Returns an iterator over all (path, version) pairs, for targeted bump enumeration.
