pub struct ProgressTracker { /* private fields */ }

Tracks execution progress and provides real-time updates

Maintains:

• Current step index
• Completed steps count
• Execution start time
• Step durations for time estimation
• Progress callbacks for UI updates

Implementations

impl ProgressTracker

pub fn new(plan: &ExecutionPlan) -> Self

Arguments

• plan - The execution plan to track

Returns

A new ProgressTracker initialized for the plan

pub fn on_progress<F>(&self, callback: F)

where F: Fn(ProgressUpdate) + Send + Sync + 'static,

Arguments

• callback - Function to call on progress updates

pub fn step_completed(&mut self, step_duration: Duration)

Update progress to the next step

Arguments

• step_duration - Duration of the completed step

pub fn step_skipped(&mut self)

Skip a step

Marks a step as skipped without recording a duration.

pub fn get_progress(&self) -> ProgressUpdate

Get the current progress update

Returns

A ProgressUpdate containing current progress information

pub fn current_step(&self) -> usize

Get the current step index (0-based)

pub fn total_steps(&self) -> usize

Get the total number of steps

pub fn completed_steps(&self) -> usize

Get the number of completed steps

pub fn progress_percentage(&self) -> f32

Get the overall progress percentage (0-100)

pub fn estimated_time_remaining(&self) -> Duration

Get the estimated time remaining

pub fn elapsed_time(&self) -> Duration

Get the total elapsed time

pub fn average_step_duration(&self) -> Duration

Get the average step duration

pub fn reset(&mut self)

Reset the progress tracker

Clears all progress data and resets to initial state.
