You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/vim-clap/crates/paths/src
    
    the code of the file until where you have to start completion: use dirs::Dirs;
use itertools::Itertools;
use serde::de::Error as DeserializeError;
use serde::{Deserialize, Deserializer, Serialize};
use std::borrow::Cow;
use s
    
pub fn current_working_dir() -> &'static PathBuf {
    static CWD: OnceLock<PathBuf> = OnceLock::new();

    CWD.get_or_init(|| {
        std::env::current_dir()
            .and_then(dunce::canonicalize)
            .expect("Couldn't determine current working directory")
    })
}
