pulse-metrics/src/batch.rs:33–39

A Batch is a collection of items that are collected over a period of time.

// A Batch is a collection of items that are collected over a period of time.
pub trait Batch<I> {
  // Push an item onto the batch. If the batch is complete, return the size.
  fn push(&mut self, item: impl Iterator<Item = I>) -> Option<usize>;

  // Finish the batch. Will only be called if there is a batch fill timeout. Return the size.
  fn finish(&mut self) -> usize;
}

// A combined batch and its size. Used for construction of both pending batches as well as entries
// in the LIFO/FIFO queue.
