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: ssh.rs
    path of file: ./repos/termscp/src/utils
    
    the code of the file until where you have to start completion: use ssh2_config::{ParseRule, SshConfig};

pub fn parse_ssh2_config(path: &str) -> Result<SshConfig, String> {
    use std::fs::File;
    use std::io::BufReader;

    let mut reader = File::open(path)
        .map_err(|e| format!("failed to open {path}: {e}"))
        .map(BufReader::new)?;
    SshConfig::default()
        .parse(&mut reader, ParseRule::ALLOW_UNKNOWN_FIELDS)
        .map_err(|e| format!("Failed to parse ssh2 config: {e}"))
}
