    Metadata details:
    filename: mod.rs
    path of file: ./repos/qdrant/lib/storage/src/content_manager/toc
    
    the code of the file until where you have to start completion: mod collection_container;
use common::types::TelemetryDetail;
mod collection_meta_ops;
mod create_collection;
mod locks;
mod point_o
    
    pub fn all_collections_sync(&self) -> Vec<String> {
        self.general_runtime
            .block_on(self.collections.read())
            .keys()
            .cloned()
            .collect()
    }
