The server host’s methods of the mod_state area, implemented by the game and reached through ServerHost.

Provided Methods

fn attachment_validate_write( &self, token: AttachmentWriteToken, ) -> Result<(), AttachmentRowError>

Side: server. Validate captured residency against the current dimension immediately before an ordinary journaled attachment write. This does not open a transaction.

fn transaction_open(&mut self) -> TransactionSeal

Side: server. Opens a transaction, nested in the open one if any (Transaction.open), and gives back the seal that ends it. host.transaction calls it; use that instead.

fn transaction_close(&mut self, seal: &TransactionSeal, commit: bool)

Side: server. Closes the transaction seal ends, committed or aborted, aborting first any opened inside it and left open. Refused when seal names no open transaction, so a mod ends only a transaction it opened. host.transaction calls it.

fn schedule_task( &mut self, delay_ticks: u32, token: u64, ) -> Result<TaskId, ScheduleError>

Side: server. Asks for Hooks::scheduled_task to be called with token after delay_ticks server ticks (MinecraftServer.tell(new TickTask(getTickCount() + delay, ..)); 0 and 1 both mean the next tick, and a paused server does not advance it). Tasks due together run in the order they were scheduled. Only inside a mod’s hook; the task belongs to that mod and is dropped with the world.

fn cancel_task(&mut self, id: TaskId) -> bool

Side: server. Withdraws a task the calling mod scheduled: true if it was still waiting.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
