Function sortery::tools::sort::is_sortable

fn is_sortable(
    path: &File, 
    exclude_type: &(&str, bool), 
    only_type: &(&str, bool)
) -> bool

Return true if:

1. path’s type is in only_type.0 and only_type.1 is true
2. path’s type is not in exclude_type.0, and only_type.1 is false

“Type” refers to the file extension, as in "jpg", "png", etc. exclude_type and only_type correspond with exclude_type and only_type in get_sorting_results, respectively.
