impl ObjectStore for LocalFileSystem

fn list_file<'life0, 'life1, 'async_trait>(
    &'life0 self,
    prefix: &'life1 str
) -> Pin<Box<dyn Future<Output = Result<FileMetaStream>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Returns all the files in path prefix

fn list_dir<'life0, 'life1, 'async_trait>(
    &'life0 self,
    prefix: &'life1 str,

    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Returns all the files in prefix if the prefix is already a leaf dir, or all paths between the prefix and the first occurrence of the delimiter if it is provided.
