pub struct RunSystemWithInput<I: 'static> { /* private fields */ }
Expand description

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§
