IntlMemoizer

intl-memoizer is a crate designed to handle lazy-initialized references to intl formatters.

The assumption is that allocating a new formatter instance is costly, and such instance is read-only during its life time, with constructor being expensive, and format/select calls being cheap.

In result it pays off to use a singleton to manage memoization of all instances of intl APIs such as PluralRules, DateTimeFormatetc. between allFluentBundle` instances.

Usage

```rust use intlmemoizer::{IntlMemoizer, Memoizable}; use uniclangid::langid;

use intl_pluralrules::{PluralRules, PluralRuleType, PluralCategory};

impl Memoizable for PluralRules { type Args = (PluralRulesType,); fn construct(lang: LanguageIdentifier, args: Self::Args) -> Self { Self::new(lang, args.0) } }

fn main() { let lang = langid!("en-US");

// A single memoizer for all languages
let mut memoizer = IntlMemoizer::new();

// A RefCell for a particular language to be used in all `FluentBundle`
// instances.
let mut en_us_memoizer = memoizer.get_for_lang(lang.clone());

// Per-call borrow
let mut en_us_memoizer_borrow = en_us_memoizer.borrow_mut();
let cb = en_us_memoizer_borrow.get::<PluralRules>((PluralRulesType::Cardinal,));
assert_eq!(cb.select(1), PluralCategory::One);

}

```
