Struct UniqueViewMut 

pub struct UniqueViewMut<'a, T: Unique> { /* private fields */ }

Exclusive view over a unique component storage.

Implementations

impl<T: Unique> UniqueViewMut<'_, T>

pub fn is_inserted(&self) -> bool

Returns true if the component was inserted before the last clear_inserted call.

pub fn is_modified(&self) -> bool

Returns true if the component was modified since the last clear_modified call.

pub fn is_inserted_or_modified(&self) -> bool

Returns true if the component was inserted or modified since the last clear_inserted or clear_modified call.

pub fn clear_inserted(self)

Removes the inserted flag on the component of this storage.

pub fn clear_modified(self)

Removes the modified flag on the component of this storage.

pub fn clear_inserted_and_modified(self)

Removes the inserted and modified flags on the component of this storage.

pub fn override_last_insertion( &mut self, new_timestamp: TrackingTimestamp, ) -> TrackingTimestamp

Replaces the timestamp starting the tracking time window for insertions.

Tracking works based on a time window. From the last time the system ran (in workloads) or since the last clear.

Sometimes this automatic time window isn’t what you need. This can happen when you want to keep the same tracking information for multiple runs of the same system.

For example if you interpolate movement between frames, you might run an interpolation workload multiple times but not change the World during its execution.
In this case you want the same tracking information for all runs of this workload which would have disappeared using the automatic window.

pub fn override_last_modification( &mut self, new_timestamp: TrackingTimestamp, ) -> TrackingTimestamp

Replaces the timestamp starting the tracking time window for modifications.

Tracking works based on a time window. From the last time the system ran (in workloads) or since the last clear.

impl<T: Unique + Clone> UniqueViewMut<'_, T>

pub fn register_clone(&mut self)

Registers the function to clone this unique component.

Trait Implementations

impl<T: Unique> AsMut<T> for UniqueViewMut<'_, T>

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T: Unique> AsRef<T> for UniqueViewMut<'_, T>
