HH\autoload_get_paths
Return all paths currently known to the autoloader
namespace HH;
function autoload_get_paths(): Container<string>;
This may or may not be all the paths in your repo. If you call
HH\autoload_set_paths() with a callback and expect that callback to
lazily load paths as it sees new symbols, this function will only return
all paths which we have seen during this request.
If native autoloading is enabled, or if every path passed to
HH\autoload_set_paths() was a valid path with all symlinks dereferenced,
then each path returned will be an absolute canonical path, with all
symlinks dereferenced.
Throws InvalidOperationException if autoloading is disabled.
