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: discovery.rs
    path of file: ./repos/wezterm/wezterm-client/src
    
    the code of the file until where you have to start completion: use crate::UnixStream;
use anyhow::Context;
use std::path::{Path, PathBuf};
use std::time::{Duration, SystemTime};

/// There's a lot more code in this windows module than I thought I would need
/// to write.  Ostensibly, we could get away with making a symlink by taking
/// the SessionName environment variable, combining it with the class name
/// and using a symlink to point to the actual path.
/// Symlinks are problematic on Windows, and the SessionName environment
/// variable may not be set.
/// It's a bit of a chore to resolve the name, and then it would be m
