Module sampler 

Sampler implementations and public sampling API.

Structs

BatchPrefetcher

Background prefetcher that fills a bounded queue with sample batches.

TripletSampler

Sampler that draws anchors from a single shared epoch cursor and then selects chunks from those records. Ingestion happens on demand when sampling.

Traits

Functions
