Struct ProgressReporter 

pub struct ProgressReporter { /* private fields */ }

Cross-process reporter handle passed to the work closure. Each call to advance is a single atomic fetch_add (Relaxed ordering; progress is observational, not a synchronization point).

Implementations

impl ProgressReporter

pub fn advance(&self, n: u64) -> u64

Add n to the progress counter. Returns the previous value. Use Relaxed because progress is observational; the done flag carries the happens-before edge.

pub fn set(&self, v: u64)

Replace the progress counter with v. Useful when the work reports absolute progress (e.g., bytes processed) rather than per-step deltas.

pub fn current(&self) -> u64

Read the current progress counter.
