Install:

[dependencies]
fsrs = { git = "https://github.com/open-spaced-repetition/rs-fsrs" }

Quickstart:

use chrono::Utc;
use fsrs::{FSRS, Card, Rating::Easy};

fn main() {
    let fsrs = FSRS::default();
    let card = Card::new();
    
    let scheduled_cards = fsrs.schedule(card, Utc::now());

    let updated_card = scheduled_cards.select_card(Easy);

    println!("{:?}", updated_card.log);
}
