Expand description

The metadata of a System.

Implementations§

§

impl SystemMeta

pub fn name(&self) -> &DebugName

Returns the system’s name

pub fn flags(&self) -> SystemStateFlags

Returns the system’s state flags

pub fn set_name(&mut self, new_name: impl Into<Cow<'static, str>>)

Sets the name of this system.

Useful to give closure systems more readable and unique names for debugging and tracing.

pub fn get_last_run(&self) -> Tick

Gets the last time this system was run.

pub fn set_last_run(&mut self, last_run: Tick)

Sets the last time this system was run.

pub fn is_send(&self) -> bool

pub fn set_non_send(&mut self)

This is irreversible.

pub fn has_deferred(&self) -> bool

Returns true if the system has deferred SystemParam’s

pub fn set_has_deferred(&mut self)

pub fn set_exclusive(&mut self)
