pub fn list_cases(fixtures_root: &Path) -> Vec<String>Expand description
Enumerate the bundled positive fixtures.
Returns the names (one per directory) under
<fixtures_root>/cases/, sorted alphabetically and excluding any
directory whose name starts with _ (the convention for negative
fixtures and other internal-only sets like _calibration/).
The list-cases subcommand calls this; the corpus subcommand
does not — corpus walks the tree directly and includes negatives.
