Struct RunSystemWithInput

pub struct RunSystemWithInput<I: SystemInput + 'static> { /* private fields */ }

The Command type for World::run_system or World::run_system_with_input.

This command runs systems in an exclusive and single threaded way. Running slow systems can become a bottleneck.

If the system needs an In<_> input value to run, it must be provided as part of the command.

There is no way to get the output of a system when run as a command, because the execution of the system happens later. To get the output of a system, use World::run_system or World::run_system_with_input instead of running the system as a command.

Implementations

impl RunSystemWithInput<()>

pub fn new(system_id: SystemId) -> Self

Creates a new Command struct, which can be added to Commands.

impl<I: SystemInput + 'static> RunSystemWithInput<I>

pub fn new_with_input(system_id: SystemId<I>, input: I::Inner<'static>) -> Self

Creates a new Command struct, which can be added to Commands in order to run the specified system with the provided In<_> input value.
