What one run of a benchmark’s entry measured.

Fields

wall: Duration

fuel_spent: u64

host_calls: u64

irreversible_writes: u64

heap: HeapStats

instructions: Option<u64>

How many instructions the run executed, on a lowered backend. None on the interpreter, which has none – the same distinction cove run --stats makes, and for the same reason.

The figure a rebuild cannot move, which is why it is reported beside the wall time rather than only inside --matrix: ADR 0029 makes an exact count repeatable where an absolute is not, and ADR 0034 asks for instruction counts by name if a gate fails. A ratio with a count beside it says whether a backend was slower per instruction or simply ran more of them.

failure: Option<String>

Some(message) when the entry returned Err or the interpreter itself failed; None when it passed.
