Struct GroupProgress 

pub struct GroupProgress {
    pub total_bytes: AtomicU64,
    pub total_bytes_completed: AtomicU64,
    pub total_transfer_bytes: AtomicU64,
    pub total_transfer_bytes_completed: AtomicU64,
    /* private fields */
}

Aggregate progress across all items, with an item registry. Owns the atomic group-level counters and a map of per-item progress.

Fields

total_bytes: AtomicU64

total_bytes_completed: AtomicU64

total_transfer_bytes: AtomicU64

total_transfer_bytes_completed: AtomicU64

Implementations

impl GroupProgress

pub fn new() -> Arc<Self>

Create a group progress tracker using default speed estimation parameters.

pub fn with_speed_config( half_life: Duration, min_observations: u32, ) -> Arc<Self>

Create a group progress tracker with explicit speed estimation parameters.

pub fn new_item( self: &Arc<Self>, id: UniqueID, name: impl Into<Arc<str>>, ) -> Arc<ItemProgressUpdater>

Create a new tracked item and register it in the items map. Returns an ItemProgressUpdater handle for the caller to report progress.

pub fn new_completion_tracker(self: &Arc<Self>) -> CompletionTracker

Create a new CompletionTracker backed by this group’s progress.

pub fn report(&self) -> GroupProgressReport

Snapshot of aggregate progress. Reads completions first (Acquire), then totals to reduce transient sampling skew.

Speed is estimated via [SpeedTracker], which uses an exponentially-weighted moving average to produce smoothed bytes-per-second rates.

This call updates internal speed-estimation state, so repeated calls are not strictly idempotent. Rate fields remain None until enough speed observations have been collected.

pub fn item_reports(&self) -> HashMap<UniqueID, ItemProgressReport>

Snapshot of all per-item progress.

pub fn item_report(&self, id: UniqueID) -> Option<ItemProgressReport>

Snapshot of one item’s progress.

pub fn assert_complete(&self)

Debug verification that all items are complete.

Trait Implementations

impl Debug for GroupProgress

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for GroupProgress

fn default() -> Self

Returns the “default value” for a type.
