pub fn bench_tmp_dir() -> Result<BenchTmpDir>Expand description
Returns the path to a temporary directory, creating it if necessary and checking ownership if it already exists. The directory is not unique for all processes, but shared for all evobench instances–which is OK both because we only do 1 run at the same time (and take a lock to ensure that), but also because we’re now currently actually also adding the pid to the file paths inside. It is wrapped since it comes with a daemon that keeps updating the directory mtime to prevent deletion by tmp cleaners.
