Feature request: Run cargo bench benchmarks via nextest

[smklein]

Motivation

"cargo nextest" has pretty much entirely replaced my usage of "cargo test", which is neat. The setup and utilities are great, and the configuration is powerful. However, when writing benchmarks, which often share a lot of logic from test utilities, things get more painful.

https://nexte.st/docs/integrations/criterion describes how "benchmarks can be run as tests" - specifically, they can run a single execution for validity - but running "benchmarks as benchmarks" is not currently possible with nextest.

Proposal

It would be nice for nextest to support a cargo nextest bench option, which runs benchmarks serially as benchmarks.

This would be distinct from cargo nextest run --benches, which does not attempt to do benchmarking, but it would allow benchmarks to utilize other features from nextest (e.g. setup scripts) for benchmarking purposes.
