Struct sid::IdVec

pub struct IdVec<ID: Identifier, T> { /* private fields */ }

Similar to Vec except that it is indexed using an Id rather than an usize index. if the stored type implements Default, IdVec can also use the set(…) method which can grow the vector to accomodate for the requested id.

Implementations

impl<ID: Identifier, T> IdVec<ID, T>

pub fn new() -> Self

Create an empty IdVec

pub fn with_capacity(size: ID::Handle) -> Self

Consume the IdVec and create a Vec.

pub fn as_vec(&self) -> &Vec<T>

Exposes the internal Vec.

pub fn len(&self) -> ID::Handle

Number of elements in the IdVec

pub fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

pub fn as_slice(&self) -> IdSlice<'_, ID, T>

Extracts a slice containing the entire vector.

pub fn as_mut_slice(&mut self) -> MutIdSlice<'_, ID, T>

Extracts a mutable slice containing the entire vector.

pub fn mut_range_to_inclusive(&mut self, id: ID) -> MutIdSlice<'_, ID, T>

pub fn nth(&self, idx: ID::Handle) -> &T

Return the nth element of the IdVec using an usize index rather than an Id (à la Vec).

pub fn iter_mut<'l>(&'l mut self) -> IterMut<'l, T>

Iterate over the elements of the IdVec

pub fn push(&mut self, elt: T) -> ID

Add an element to the IdVec and return its Id. This method can cause the storage to be reallocated.

pub fn insert(&mut self, id: ID, elt: T)

Inserts an element at position id within the vector, shifting all elements after it to the right.

pub fn insert_slice(&mut self, id: ID, elts: &[T])

where T: Clone,

where T: Clone,

Clones and appends all elements in a slice to the vector.

pub fn reserve(&mut self, additional: ID::Handle)

Reserves capacity for at least additional more elements to be inserted in the given vector.

pub fn shrink_to_fit(&mut self)

Shrinks the capacity of the vector as much as possible.

pub fn clear(&mut self)

Drop all of the contained elements and clear the IdVec’s storage.

pub fn remove(&mut self, index: ID) -> T

Removes and returns the element at position index within the vector, shifting all elements after it to the left.

pub fn swap_remove(&mut self, index: ID) -> T

Removes an element from the vector and returns it. The removed element is replaced by the last element of the vector.

pub fn has_id(&self, id: ID) -> bool

pub fn last_id(&self) -> Option<ID>

pub fn ids(&self) -> IdRange<ID::Tag, ID::Handle>

impl<ID: Identifier, T: Default> IdVec<ID, T>

pub fn set(&mut self, id: ID, val: T)

Set the value for a certain Id, possibly adding default values if the Id’s index is Greater than the size of the underlying vector.

impl<T: Default, ID: Identifier> IdVec<ID, T>

pub fn resize(&mut self, size: ID::Handle)

pub fn with_len(n: ID::Handle) -> Self

Creates an IdVec with an n elements initialized to Default::default.
