how to define `AppStrategy` in one place only?

[nschloe]

In the docs, I find

use etcetera::{choose_app_strategy, AppStrategy, AppStrategyArgs};

let strategy = choose_app_strategy(AppStrategyArgs {
    top_level_domain: "org".to_string(),
    author: "Acme Corp".to_string(),
    app_name: "Frobnicator Plus".to_string(),
}).unwrap();

let config_dir = strategy.config_dir();

Now, I'd like to get different dirs in different parts of my code. To this end, I'd like to define the strategy once somewhere in my code and then draw from it. Is this

use etcetera::{AppStrategy, AppStrategyArgs, choose_app_strategy};

pub fn get_dirs() -> impl AppStrategy {
    choose_app_strategy(AppStrategyArgs {
        top_level_domain: "com".to_string(),
        author: "YourName".to_string(),
        app_name: "MyApp".to_string(),
    })
    .expect("Failed to create app strategy")
}

the recommended way of doing it? Perhaps it's a little overkill to re-choose the strategy over and over again.

For a global config like this, I would say using LazyCell is the way to go. LazyCell initializes the config on first use & returns it to all callers later on.
