Function ommui_file_loading::load_directory_listing

pub fn load_directory_listing(pattern: &str) -> Result<IndexSet<String>, Error>

Load a IndexSet from a directory, one entry for each glob match.

This function takes a glob pattern that determines which entries get put into the set. The entries in the set contain the parts that differ from the pattern.

For example if the directory /srv/data contains the files hello.json, world.json and readme.txt, and the glob pattern is /srv/data/*.json, then the resulting set will contain hello and world.
