If level.toml exists, it will be loaded (the provided seed is ignored). Otherwise, new data will be created with the provided seed.

pub async fn load_seed_or_default( world_dir: Option<impl AsRef<Path>>, default_seed: i64, ) -> Result<i64>

Loads the saved world seed from level.toml, or returns the provided default.

pub const fn data(&self) -> &LevelData

Gets a reference to the level data.

pub const fn data_mut(&mut self) -> &mut LevelData

Gets a mutable reference to the level data and marks it as dirty.

pub const fn is_dirty(&self) -> bool

Returns whether the data has been modified since last save.

pub const fn mark_dirty(&mut self)

Marks the data as dirty (needs saving).

pub async fn save(&mut self) -> Result<()>

Saves the level data to disk if it has been modified.

pub const fn seed(&self) -> i64

Gets the seed.

pub const fn game_time(&self) -> i64

Gets the game time.

pub const fn set_game_time(&mut self, time: i64)

Sets the game time.

pub(crate) const fn world_clocks(&self) -> &WorldClockManager

Returns this world’s clock manager.

pub(crate) const fn world_clocks_mut(&mut self) -> &mut WorldClockManager

Returns this world’s mutable clock manager and marks level data dirty.
