Struct EntityVec

pub struct EntityVec<Idx: EntityRef, T: Clone + Debug>(/* private fields */);

Implementations

impl<Idx: EntityRef, T: Clone + Debug> EntityVec<Idx, T>

pub fn push(&mut self, t: T) -> Idx

Add a new entity, returning its assigned index.

pub fn len(&self) -> usize

Get the number of entities in this entity space.

pub fn iter(&self) -> impl DoubleEndedIterator<Item = Idx>

Get an iterator over the index-space.

pub fn values(&self) -> impl DoubleEndedIterator<Item = &T>

Get an iterator over (borrows of) entity values.

pub fn values_mut(&mut self) -> impl DoubleEndedIterator<Item = &mut T>

Get an iterator over (mutable borrows of) entity values.

pub fn entries(&self) -> impl DoubleEndedIterator<Item = (Idx, &T)>

Get an iterator over index, borrow-of-entity tuples.

pub fn entries_mut(&mut self) -> impl Iterator<Item = (Idx, &mut T)>

Get an iterator over index, mutable-borrow-of-entity tuples.

pub fn get(&self, idx: Idx) -> Option<&T>

Typesafe element access, returning None if idx is the invalid index.

pub fn get_mut(&mut self, idx: Idx) -> Option<&mut T>

Typesafe mutable element access, returning None if idx is the invalid index.

pub fn into_vec(self) -> Vec<T>

Convert this EntityVec into the underlying Vec and return it.
