transparent-reader

To compute a hash on a streaming byte pipeline without buffering, you can wrap your Rust Read source with a transparent reader. It updates the hasher during each read operation, and you call finalize to retrieve the computed digest.

The best way to count bytes read from a Rust Read consumer while keeping the data flow invisible is to use a transparent reader wrapper. It updates a byte counter on each read without materializing the full stream.

Yes, you can apply multiple side effects like checksums and byte counts to a single streaming data pipeline. Transparent readers are composable, allowing you to stack multiple wrappers to apply several side effects simultaneously.

No, a transparent reader wrapper does not affect the original data consumed by the inner reader. It intercepts streaming bytes to compute side effects like hashes or byte counts while keeping the inner reader hidden from the consumer.

You should not use a transparent reader for streaming data observation if your use case requires buffering or materializing the full stream. It is specifically designed to compute side effects without buffering, keeping the data flow invisible to the consumer.
