Struct PullProgressAggregator 

pub struct PullProgressAggregator { /* private fields */ }

Folds a stream of PullProgress into a single overall percent, so a host shows one progress bar for a multi-layer download. A streaming pull reports completed/total per digest and resends a digest’s line as it grows; this keeps the latest figures per digest, so the overall percent is 100 * Σcompleted / Σtotal across the digests seen so far.

Implementations

impl PullProgressAggregator

pub fn update(&mut self, progress: &PullProgress) -> Option<f64>

Fold one progress update in (only digest lines carrying a total count) and return the overall percent so far — None until any byte total is known (e.g. during the manifest phase).

pub fn percent(&self) -> Option<f64>

Overall percent across every digest seen, clamped to 0–100; None until a total is known. A just-finished layer can momentarily report completed > total, so the ratio is capped.
