Struct VecGroup

pub struct VecGroup<E: Entity, T = UnitFor<E>> { /* private fields */ }

Analogous to alloc::vec::Vec for groups.

Implementations

impl<E: Entity, T> VecGroup<E, T>

pub fn from_inner(inner: GroupFor<E, Vec<T>>) -> Self

Create a new VecGroup from a group of alloc::vec::Vec.

pub fn into_inner(self) -> GroupFor<E, Vec<T>>

Consume self to return a group of alloc::vec::Vec.

pub fn as_inner_ref(&self) -> GroupFor<E, &Vec<T>>

Return a reference to the inner group of alloc::vec::Vec.

pub fn as_inner_mut(&mut self) -> GroupFor<E, &mut Vec<T>>

Return a mutable reference to the inner group of alloc::vec::Vec.

pub fn as_slice(&self) -> SliceGroup<'_, E, T>

Return a SliceGroup view over the elements of self.

pub fn as_slice_mut(&mut self) -> SliceGroupMut<'_, E, T>

Return a SliceGroupMut mutable view over the elements of self.

pub fn new() -> Self

Create an empty VecGroup.

pub fn len(&self) -> usize

Returns the length of the vector group.

pub fn capacity(&self) -> usize

Returns the capacity of the vector group.

pub fn reserve(&mut self, additional: usize)

Reserve enough capacity for extra additional elements.

pub fn reserve_exact(&mut self, additional: usize)

Reserve exactly enough capacity for extra additional elements.

pub fn try_reserve(&mut self, additional: usize) -> Result<(), TryReserveError>

Try to reserve enough capacity for extra additional elements.

pub fn try_reserve_exact( &mut self, additional: usize, ) -> Result<(), TryReserveError>

Try to reserve exactly enough capacity for extra additional elements.

pub fn truncate(&mut self, len: usize)

Truncate the length of the vector to len.

pub fn clear(&mut self)

Clear the vector, making it empty.

pub fn resize(&mut self, new_len: usize, value: GroupFor<E, T>)

where T: Clone,

Resize the vector to new_len, filling the new elements with value.

pub fn resize_with(&mut self, new_len: usize, f: impl FnMut() -> GroupFor<E, T>)

Resize the vector to new_len, filling the new elements with the output of f.

pub fn push(&mut self, value: GroupFor<E, T>)

Push a new element to the end of self.

pub fn pop(&mut self) -> Option<GroupFor<E, T>>

Remove a new element from the end of self, and return it.

pub fn remove(&mut self, index: usize) -> GroupFor<E, T>

Remove a new element from position index, and return it.
