pub struct SystemSets { /* private fields */ }
Expand description
Container for system sets in a schedule.
Implementations§
Source§impl SystemSets
impl SystemSets
Sourcepub fn contains(&self, set: impl SystemSet) -> bool
pub fn contains(&self, set: impl SystemSet) -> bool
Returns true
if the given set is present in this container.
Sourcepub fn get(&self, key: SystemSetKey) -> Option<&dyn SystemSet>
pub fn get(&self, key: SystemSetKey) -> Option<&dyn SystemSet>
Returns a reference to the system set with the given key, if it exists.
Sourcepub fn get_key_or_insert(&mut self, set: InternedSystemSet) -> SystemSetKey
pub fn get_key_or_insert(&mut self, set: InternedSystemSet) -> SystemSetKey
Returns the key for the given system set, inserting it into this container if it does not already exist.
Sourcepub fn has_conditions(&self, key: SystemSetKey) -> bool
pub fn has_conditions(&self, key: SystemSetKey) -> bool
Returns true
if the system set with the given key has conditions.
Sourcepub fn get_conditions(
&self,
key: SystemSetKey,
) -> Option<&[ConditionWithAccess]>
pub fn get_conditions( &self, key: SystemSetKey, ) -> Option<&[ConditionWithAccess]>
Returns a reference to the conditions for the system set with the given key, if it exists.
Sourcepub fn get_conditions_mut(
&mut self,
key: SystemSetKey,
) -> Option<&mut Vec<ConditionWithAccess>>
pub fn get_conditions_mut( &mut self, key: SystemSetKey, ) -> Option<&mut Vec<ConditionWithAccess>>
Returns a mutable reference to the conditions for the system set with the given key, if it exists.
Sourcepub fn iter(
&self,
) -> impl Iterator<Item = (SystemSetKey, &dyn SystemSet, &[ConditionWithAccess])>
pub fn iter( &self, ) -> impl Iterator<Item = (SystemSetKey, &dyn SystemSet, &[ConditionWithAccess])>
Returns an iterator over all system sets in this container, along with their conditions.
Sourcepub fn insert(
&mut self,
set: InternedSystemSet,
new_conditions: Vec<Box<dyn ReadOnlySystem<In = (), Out = bool>>>,
) -> SystemSetKey
pub fn insert( &mut self, set: InternedSystemSet, new_conditions: Vec<Box<dyn ReadOnlySystem<In = (), Out = bool>>>, ) -> SystemSetKey
Inserts conditions for a system set into the container, and queues the
newly added conditions to be initialized later in SystemSets::initialize
.
If the set was not already present in the container, it is added automatically.
We have to defer initialization of system set conditions in the container
until we have &mut World
access, so we store these in a list until
SystemSets::initialize
is called. This is usually done upon the
first run of the schedule.
Sourcepub fn is_initialized(&self) -> bool
pub fn is_initialized(&self) -> bool
Returns true
if all system sets’ conditions in this container have
been initialized.
Sourcepub fn initialize(&mut self, world: &mut World)
pub fn initialize(&mut self, world: &mut World)
Initializes all system sets’ conditions that have not been initialized yet. Because a system set’s conditions may be appended to multiple times, we track which conditions were added since the last initialization and only initialize those.
