Struct AutoInsertApplyDeferredPass

pub struct AutoInsertApplyDeferredPass { /* private fields */ }

A ScheduleBuildPass that inserts ApplyDeferred systems into the schedule graph when there are Deferred in one system and there are ordering dependencies on that system. Commands is one such deferred buffer.

This pass is typically automatically added to the schedule. You can disable this by setting ScheduleBuildSettings::auto_insert_apply_deferred to false. You may want to disable this if you only want to sync deferred params at the end of the schedule, or want to manually insert all your sync points.

Trait Implementations

impl Debug for AutoInsertApplyDeferredPass

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AutoInsertApplyDeferredPass

fn default() -> AutoInsertApplyDeferredPass

Returns the “default value” for a type.

impl ScheduleBuildPass for AutoInsertApplyDeferredPass

type EdgeOptions = IgnoreDeferred

Custom options for dependencies between sets or systems.

fn add_dependency( &mut self, from: NodeId, to: NodeId, options: Option<&Self::EdgeOptions>, )

Called when a dependency between sets or systems was explicitly added to the graph.

fn build( &mut self, _world: &mut World, graph: &mut ScheduleGraph, dependency_flattened: &mut DiGraph, ) -> Result<(), ScheduleBuildError>

The implementation will be able to modify the ScheduleGraph here.

fn collapse_set( &mut self, set: NodeId, systems: &[NodeId], dependency_flattened: &DiGraph, ) -> impl Iterator<Item = (NodeId, NodeId)>

Called while flattening the dependency graph. For each set, this method is called with the systems associated with the set as well as an immutable reference to the current graph. Instead of modifying the graph directly, this method should return an iterator of edges to add to the graph.
