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: removed_commands.rs
    path of file: ./repos/nushell/crates/nu-command/src/removed
    
    the code of the file until where you have to start completion: use std::collections::HashMap;

/// Return map of <removed_command_name, new_command_name>
/// This covers simple removed commands nicely, but it's not great for deprecating
/// subcommands like `foo bar` where `foo` is still a 
    
pub fn removed_commands() -> HashMap<String, String> {
    [
        ("fetch".to_string(), "http get".to_string()),
        ("post".to_string(), "http post".to_string()),
        ("benchmark".to_string(), "timeit".to_string()),
    ]
    .into_iter()
    .collect()
