Struct ProgressTracker 

pub struct ProgressTracker {
    pub images_total: usize,
    pub variants_total: usize,
    /* private fields */
}

Tracks build progress across the three pipeline stages.

Created after scan completes (when totals are known). Call [on_image_processed] for each ProcessEvent::ImageProcessed to advance the counters.

Fields

images_total: usize

variants_total: usize

Implementations

impl ProgressTracker

pub fn new(images_total: usize, variants_per_image: usize) -> Self

Create a tracker from the scan results.

variants_per_image is the config-based estimate: responsive_sizes.len() + 1 (thumbnail) + full_index_flag.

pub fn with_totals(images_total: usize, variants_total: usize) -> Self

Create a tracker with pre-computed totals (for per-album-config accuracy).

Use this when albums have different configs so variants_total cannot be derived from a single variants_per_image factor.

pub fn scan_complete(&self) -> ProgressEvent

Build the scan-complete progress event (stage boundary).

pub fn on_image_processed(&mut self, variant_count: usize) -> ProgressEvent

Record a completed image and return the updated progress event.

variant_count is the actual number of variants this image produced (taken from ProcessEvent::ImageProcessed.variants.len()).

pub fn generate_started(&self) -> ProgressEvent

Build the generate-started progress event (stage boundary).
