Benchmarks not running when specifying benchmark name

[TrAyZeN]

When specifying benchmark name with cargo bench BENCHNAME benchmarks are not run. It used to work, but I encountered this issue and I can reproduce it on criterion example.

Here is the output of cargo bench my_benchmark on criterion example:

$ cargo bench my_benchmark
    Finished bench [optimized] target(s) in 0.02s
     Running unittests src/lib.rs (target/release/deps/mycrate-85c68243aaad160d)

test result: ok. 0 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s

Here are the files to reproduce:

• Cargo.toml

  
  [package]
  name = "mycrate"
  version = "0.1.0"
  edition = "2021"

pub fn fibonacci(n: u64) -> u64 {
    match n {
        0 => 1,
        1 => 1,
        n => fibonacci(n - 1) + fibonacci(n - 2),
    }
}

  use criterion::{black_box, criterion_group, criterion_main, Criterion};
  use mycrate::fibonacci;

pub fn criterion_benchmark(c: &mut Criterion) { c.bench_function("fib 20", |b| b.iter(|| fibonacci(black_box(20)))); }

criterion_group!(benches, criterion_benchmark); criterion_main!(benches);
