Struct BoosterSimulator 

pub struct BoosterSimulator<'a> { /* private fields */ }

Simulates opening MTG booster packs using the MTGJSON booster configuration data.

The simulator reads from the set booster parquet tables (content weights, contents, sheet cards, and sheet metadata) to faithfully reproduce the distribution of cards in sealed product.

Implementations

impl<'a> BoosterSimulator<'a>

pub fn new(conn: &'a Connection) -> Self

Create a new BoosterSimulator bound to the given connection.

pub fn available_types(&self, set_code: &str) -> Result<Vec<String>>

Return the available booster type names for a set (e.g. ["draft", "collector"]).

Returns an empty vector if the set has no booster configuration data.

pub fn open_pack( &self, set_code: &str, booster_type: &str, ) -> Result<Vec<Value>>

Open a single booster pack and return the card data for every card in the pack.

Performs weighted random selection of a pack template and then weighted random selection of cards from each sheet in the template. Returns a vector of card JSON objects fetched from the cards view.

pub fn open_box( &self, set_code: &str, booster_type: &str, packs: usize, ) -> Result<Vec<Vec<Value>>>

Open a box containing packs booster packs.

Returns a vector of packs, where each pack is a vector of card JSON objects.

pub fn sheet_contents( &self, set_code: &str, booster_type: &str, sheet_name: &str, ) -> Result<Option<HashMap<String, i64>>>

Get the contents of a specific sheet as a {uuid: weight} map.

Returns None if the sheet does not exist for the given set/booster type.
