Struct SystemSet 

pub struct SystemSet { /* private fields */ }

A named set of systems for grouping and batch configuration.

System sets allow applying ordering constraints and run conditions to multiple systems at once.

Implementations

impl SystemSet

pub fn new(name: impl Into<String>) -> Self

Creates a new empty system set.

pub fn with_capacity(name: impl Into<String>, capacity: usize) -> Self

Creates a new system set with pre-allocated capacity.

pub fn name(&self) -> &str

Returns the name of this set.

pub fn add(&mut self, system: SystemId) -> bool

Adds a system to this set.

Returns true if the system was added, false if already present.

pub fn remove(&mut self, system: SystemId) -> bool

Removes a system from this set.

Returns true if the system was removed, false if not present.

pub fn contains(&self, system: SystemId) -> bool

Returns true if this set contains the given system.

pub fn len(&self) -> usize

Returns the number of systems in this set.

pub fn is_empty(&self) -> bool

Returns true if this set is empty.

pub fn iter(&self) -> impl Iterator<Item = SystemId> + '_

Returns an iterator over systems in this set.

pub fn clear(&mut self)

Clears all systems from this set.
