Function quick_list 

pub fn quick_list(
    path: &Path,
    config: Option<&ScanConfig>,
) -> Result<FileTree, ScanError>

Create a quick, non-recursive directory listing for immediate display. This function reads only the immediate children of a directory without recursing into subdirectories. Directory sizes will be 0 (unknown).

Warnings encountered during the listing are included in the returned FileTree rather than being silently dropped.

The config parameter controls whether hidden files are shown. Pass None to use a default config (hidden files included).
