Struct apecs::LazyComponents

pub struct LazyComponents(_);

Add components lazily, at the time of your choosing.

Used in instances where you can’t apply changes to Components because of a borrow conflict (eg while iterating over a component query).

Implementations

impl LazyComponents

pub fn insert_bundle<B: IsBundle + 'static>(
    &mut self,
    entity_id: usize,
    bundle: B
)

Inserts the bundled components for the given entity.

pub fn insert_component<T: Send + Sync + 'static>(
    &mut self,
    entity_id: usize,
    component: T
)

Insert a single component for the given entity.

pub fn remove<B: IsBundle + 'static>(&mut self, entity_id: usize)

Remove all components of the given entity and return them as a typed bundle.

pub fn remove_component<T: Send + Sync + 'static>(&mut self, entity_id: usize)

Remove a single component from the given entity, returning it if the entity had a component of that type.

pub fn apply(self, components: &mut Components)

Apply changes.

Panics

Panics if the application of any changes panic.

Trait Implementations

impl Default for LazyComponents

fn default() -> LazyComponents

Returns the “default value” for a type.

impl Extend<Box<dyn FnOnce(&mut Components) + 'static, Global>> for LazyComponents

fn extend<T: IntoIterator<Item = Box<dyn FnOnce(&mut Components)>>>(
    &mut self,
    iter: T
)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl IntoIterator for LazyComponents

type Item = Box<dyn FnOnce(&mut Components) + 'static, Global>

The type of the elements being iterated over.

type IntoIter = IntoIter<<LazyComponents as IntoIterator>::Item, Global>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
