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: help_aliases.rs
    path of file: ./repos/nushell/crates/nu-command/src/help
    
    the code of the file until where you have to start completion: use crate::help::highlight_search_in_table;
use nu_color_config::StyleCompute
    
    fn examples(&self) -> Vec<Example> {
        vec![
            Example {
                description: "show all aliases",
                example: "help aliases",
                result: None,
            },
            Example {
                description: "show help for single alias",
                example: "help aliases my-alias",
                result: None,
            },
            Example {
                description: "search for string in alias names and usages",
                example: "help aliases --find my-alias",
                result: None,
            },
        ]
    }
