Description
I have a simple project with a benchmark using Rust's built-in #[bench] functionality written alongside unit tests, in the same file as the code I'm testing.
Usually I run benchmarks using:
cargo bench
Or if I only want to run some functions:
cargo bench <name_of_function>
But when I try to run cargo-instruments, I get the following error:
$ cargo instruments -t time --bench
error: The argument '--bench <NAME>' requires a value but none was supplied
USAGE:
cargo instruments --template <TEMPLATE> <--example <NAME>|--bin <NAME>|--bench <NAME>>
For more information try --help
I don't know what I should put in as the <NAME> since the none of the following work:
cargo instruments -t time --bench <name_of_function>
cargo instruments -t time --bench <name_of_crate>
cargo instruments -t time --bench <name_of_crate>-test
cargo instruments -t time --bench <name_of_crate>-bench
cargo instruments -t time --bench crate
cargo instruments -t time --bench libtest
cargo instruments -t time --bench test
cargo instruments -t time --bench bench
cargo instruments -t time --bench benches
cargo instruments -t time --bench ''
cargo instruments -t time --bench -
I always get the following error:
Failed no bench target named `<the_name_i_tried>`.
no bench target named `<the_name_i_tried>`.
I get a similar error if I try to specify a name when with --bench using cargo bench:
$ cargo bench --bench <name_of_crate>
error: no bench target named `<name_of_crate>`.
However I can call cargo bench without arguments, or specify --bins, --bin <name_of_crate>, or --benches to run my benchmark without profiling.
Any ideas?
