Struct easy_repl::command::Command

pub struct Command<'a> {
    pub description: String,
    pub args_info: Vec<String>,
    pub handler: Box<Handler<'a>>,
}

Single command that can be called in the REPL.

Though it is possible to construct it by manually, it is not advised. One should rather use the provided command! macro which will generate appropriate arguments validation and args_info based on passed specification.
