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: create.rs
    path of file: ./repos/ockam/implementations/rust/ockam/ockam_command/src/space
    
    the code of the file until where you have to start completion: use clap::Args;
use colorful::Colorful;
use miette::miette;

    
fn validate_space_name(s: &str) -> Result<String, String> {
    match api::validate_cloud_resource_name(s) {
        Ok(_) => Ok(s.to_string()),
        Err(_e) => Err(String::from(
            "space name can contain only alphanumeric characters and the '-', '_' and '.' separators. \
            Separators must occur between alphanumeric characters. This implies that separators can't \
            occur at the start or end of the name, nor they can occur in sequence.",
        ))
    }
