pub struct IndexVec<I: Idx, T> {
pub raw: Vec<T>,
/* private fields */
}
Expand description
A Vec that only accepts indices of a specific type.
This is a thin wrapper around Vec
, to the point where the backing vec is a
public property (called raw
). This is in part because I know this API is
not a complete mirror of Vec’s (patches welcome). In the worst case, you can
always do what you need to the Vec itself.
Note that this implements Deref/DerefMut to IndexSlice
, and so all the
methods on IndexSlice are available as well. See it’s documentation for some
further information.
The following extensions to the Vec APIs are added (in addition to the ones mentioned in IndexSlice’s documentation):
IndexVec::next_idx
,IndexSlice::last_idx
give the next and most recent index returned bypush
.IndexVec::push
returns the index the item was inserted at.
Fields§
