Struct UniqueOrDefaultViewMut 

pub struct UniqueOrDefaultViewMut<'v, T: Unique + Default>(/* private fields */);

Exclusive view over a unique storage of a component with a default value.

If the component is not already present, its default value will be inserted.

Trait Implementations

impl<'v, T: Unique + Default + Send + Sync> BorrowInfo for UniqueOrDefaultViewMut<'v, T>

fn borrow_info(info: &mut Vec<TypeInfo>)

This information is used during workload creation to determine which systems can run in parallel.

fn enable_tracking( enable_tracking_fn: &mut Vec<fn(&AllStorages) -> Result<(), GetStorage>>, )

Enable tracking on the World where this storage is borrowed.

impl<'v, T: Unique + Default> Deref for UniqueOrDefaultViewMut<'v, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'v, T: Unique + Default> DerefMut for UniqueOrDefaultViewMut<'v, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'view, 'de: 'view, T> Deserialize<'de> for UniqueOrDefaultViewMut<'view, T>

where T: DeserializeOwned + Unique + Default,

Available on crate feature serde1 only.

fn deserialize<D>(_deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, T: Unique + Default + Serialize> Serialize for UniqueOrDefaultViewMut<'a, T>

Available on crate feature serde1 only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'v, T: Unique + Default + Send + Sync> WorldBorrow for UniqueOrDefaultViewMut<'v, T>

type WorldView<'a> = UniqueOrDefaultViewMut<'a, T>

fn world_borrow( world: &World, last_run: Option<TrackingTimestamp>, current: TrackingTimestamp, ) -> Result<Self::WorldView<'_>, GetStorage>

This function is where the actual borrowing happens.
