Struct ChunkTicketManager 

pub struct ChunkTicketManager {
    tickets: FxHashMap<ChunkPos, SmallVec<[ChunkTicket; 4]>>,
    levels: FxHashMap<ChunkPos, ChunkTicketLevel>,
    simulation_levels: FxHashMap<ChunkPos, ChunkTicketLevel>,
    dirty: bool,
    changes: Vec<LevelChange>,
}

Chunk ticket propagation. Lower levels = higher priority. Multiple tickets per position supported.

Fields

tickets: FxHashMap<ChunkPos, SmallVec<[ChunkTicket; 4]>>

levels: FxHashMap<ChunkPos, ChunkTicketLevel>

simulation_levels: FxHashMap<ChunkPos, ChunkTicketLevel>

dirty: bool

changes: Vec<LevelChange>

Tracks changes from the last run_all_updates() call.

Implementations

impl ChunkTicketManager

pub fn new() -> Self

pub fn add_ticket(&mut self, pos: ChunkPos, ticket: ChunkTicket)

Adds a ticket source. Multiple tickets can exist at the same position.

pub fn remove_ticket(&mut self, pos: ChunkPos, ticket: ChunkTicket) -> bool

Removes one ticket matching (pos, ticket). Returns true if found.

pub fn remove_all_tickets_at(&mut self, pos: ChunkPos) -> bool

Removes all tickets at position. Returns true if any were present.

pub fn get_ticket(&self, pos: ChunkPos) -> Option<ChunkTicketLevel>

Returns the minimum ticket level at position.

pub fn tickets_at( &self, pos: ChunkPos, ) -> impl Iterator<Item = ChunkTicket> + '_

Iterator over the tickets currently held at pos.

pub fn tickets(&self) -> impl Iterator<Item = (ChunkPos, ChunkTicketLevel)> + '_

Iterator over (position, min_level) for all ticket sources.

pub fn ticket_count(&self) -> usize

pub fn ticket_position_count(&self) -> usize

pub fn run_all_updates(&mut self) -> &[LevelChange]

Propagates all tickets. Only runs if dirty. Returns a slice of changes (added/updated/removed levels).

pub(crate) fn take_changes(&mut self) -> Vec<LevelChange>

Takes the change list produced by the last propagation pass.

pub(crate) fn recycle_changes(&mut self, changes: Vec<LevelChange>)

Returns a drained change buffer for reuse by the next propagation pass.

fn record_simulation_only_changes( &mut self, old_levels: &FxHashMap<ChunkPos, ChunkTicketLevel>, old_simulation_levels: &FxHashMap<ChunkPos, ChunkTicketLevel>, )

pub fn get_level(&self, pos: ChunkPos) -> Option<ChunkTicketLevel>

Returns the propagated level at position. Call run_all_updates() first.

pub fn get_simulation_level(&self, pos: ChunkPos) -> Option<ChunkTicketLevel>

Returns the propagated simulation level at position. Call run_all_updates() first.

fn clear(&mut self)

pub fn iter_levels( &self, ) -> impl Iterator<Item = (ChunkPos, ChunkTicketLevel)> + '_

pub fn iter_simulation_levels( &self, ) -> impl Iterator<Item = (ChunkPos, ChunkTicketLevel)> + '_

impl Default for ChunkTicketManager

fn default() -> Self

Returns the “default value” for a type.
