Enum DirtySpecializationSystems 

pub enum DirtySpecializationSystems {
    Clear,
    CheckForChanges,
    CheckForRemovals,
}

A SystemSet that contains all systems that mutate the DirtySpecializations resource and other resources that wrap that type.

These systems must run in order.

Variants

Clear

Systems that clear out DirtySpecializations types in preparation for a new frame.

CheckForChanges

Systems that add entities that need to be re-specialized to DirtySpecializations.

CheckForRemovals

Systems that determine which entities need to be removed from render phases and write the results to DirtySpecializations.

The set of entities that need to be removed from the render phases can only be determined after all systems in DirtySpecializationSystems::CheckForChanges have run. That’s because these systems check RemovedComponents resources, and they have to be able to distinguish between the case in which an entity was truly made unrenderable and the case in which an entity appeared in a RemovedComponents table simply because its material type changed.

Trait Implementations

impl Clone for DirtySpecializationSystems

fn clone(&self) -> DirtySpecializationSystems

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirtySpecializationSystems

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for DirtySpecializationSystems

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DirtySpecializationSystems

fn eq(&self, other: &DirtySpecializationSystems) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SystemSet for DirtySpecializationSystems

where Self: 'static + Send + Sync + Clone + Eq + Debug + Hash,

fn dyn_clone(&self) -> Box<dyn SystemSet>

Clones this SystemSet.

fn system_type(&self) -> Option<TypeId>

Returns Some if this system set is a SystemTypeSet.

fn is_anonymous(&self) -> bool

Returns true if this system set is an AnonymousSet.

fn intern(&self) -> Interned<dyn SystemSet>

where Self: Sized,

Returns an Interned value corresponding to self.
