Struct DirtyTracker 

pub struct DirtyTracker { /* private fields */ }

Tracks field modifications during handler execution with granular change information. This replaces the simple HashSet approach to enable delta-only emissions.

Implementations

impl DirtyTracker

pub fn new() -> Self

Create a new empty DirtyTracker

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

Mark a field as replaced (full value will be emitted)

pub fn mark_appended(&mut self, path: &str, value: Value)

Record an appended value for a field

pub fn is_empty(&self) -> bool

Check if there are any changes tracked

pub fn len(&self) -> usize

Get the number of changed fields

pub fn iter(&self) -> impl Iterator<Item = (&String, &FieldChange)>

Iterate over all changes

pub fn dirty_paths(&self) -> HashSet<String>

Get a set of all dirty field paths (for backward compatibility)

pub fn into_changes(self) -> HashMap<String, FieldChange>

Consume the tracker and return the changes map

pub fn changes(&self) -> &HashMap<String, FieldChange>

Get a reference to the changes map

pub fn appended_paths(&self) -> Vec<String>

Get paths that were appended (not replaced)
