Extension trait that adds rollback checkpoint-related methods to Bevy’s World.

Required Methods

fn checkpoint<P: Pipeline>(&mut self, pipeline: P)

Creates a checkpoint for rollback and stores it in Checkpoints.

fn rollback<P: Pipeline>( &mut self, pipeline: P, checkpoints: isize, ) -> Result<(), Error>

Rolls back / forward the World state.

Errors

• See Error

fn rollback_with<P: Pipeline>( &mut self, pipeline: P, checkpoints: isize, registry: &TypeRegistry, ) -> Result<(), Error>

Rolls back / forward the World state using the given TypeRegistry.

Errors

• See Error

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
