Module score 

Scoring and winners for stuffr bench. Pure: no I/O, no timing.

Each metric (bytes_out, compress_ns, decompress_ns) is scored best / value over the rows that succeeded, a value of 0 counting as 1. balance is the mean of the three scores. Failed rows score None and never win. Ties go to the smaller bytes_out, then to the earlier row.

Structs

Measured

What one successful format/level run produced.

Memory

Peak resident memory of one row, from the untimed memory runs. A number is None when its run failed; error then says why (a refusal by --memory-limit reads differently from a crash).

Row

One line of the table. level is None for codecs without levels (lz4, snappy). backend is "c" or "pure": which implementation of the format this build ran (levels::backend_of).

Winners

Indices into the rows slice, one per column; None when no row succeeded.

Enums

Outcome

The result of one row: measured, or failed with a reason.

Functions

balance_scores

The balance score of every row: the mean of the three per-metric scores, None for a failed row.

winners

The winner of each column. Ties go to the smaller bytes_out, then to the earlier row. least_memory considers only rows with both numbers.
