Struct SystemGraph

pub struct SystemGraph { /* private fields */ }

A builder for creating graphs of dependent parallel execution within a SystemStage.

Please see the crate level docs for examples on how to use this type.

This type implements Clone by wrapping a Rc and can be safely clone and still have the clone refer to the same underlying graph.

Implementations

impl SystemGraph

pub fn new() -> Self

Creates a new, empty SystemGraph.

pub fn root<Params>( &self, system: impl IntoSystemDescriptor<Params>, ) -> SystemGraphNode

Creates a new SystemGraph with specific graph ID. Should be exclusively for testing purposes. Creates a root graph node without any dependencies. A graph can have multiple distinct root nodes.

pub fn is_same_graph(&self, other: &Self) -> bool

Checks if two graphs instances point to the same logical underlying graph.

Trait Implementations

impl Clone for SystemGraph

fn clone(&self) -> SystemGraph

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for SystemGraph

fn default() -> Self

Returns the “default value” for a type.

impl From<SystemGraph> for SystemSet

A draining conversion to SystemSet. All other clones of the same graph will be empty afterwards.

fn from(graph: SystemGraph) -> Self

Converts to this type from the input type.
