Struct index_vec::IndexSlice

#[repr(transparent)]
pub struct IndexSlice<I: Idx, T: ?Sized> {
    pub raw: T,
    // some fields omitted
}

A slice that only accepts indices of a specific type. Note that the intended usage is as IndexSlice<I, [T]>.

This is a thin wrapper around a [T], to the point where the backing 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 slice itself.

Some notes on the APIs

• Most of the Slice APIs are present.

  • Any that aren't can be trivially accessed on the underlying raw field, which is public.

• Apis that take or return usizes referring to the positions of items were replaced with ones that take Idx.

• Apis that take R: RangeBounds<usize> take an IdxRangeBounds<I>, which is basically a RangeBounds<I>.

• Apis that take SliceIndex<usize> take an IdxSliceIndex<I>, which is basically a SliceIndex<I>.

• Most iterator functions where the_iter().enumerate() would refer to indices have been given _enumerated variants. E.g. IndexSlice::iter_enumerated, etc. This is because v.iter().enumerate() would be (usize, &T), but you want (I, &T).

The following extensions are added:

• IndexSlice::indices: an Iterator over the indices of type I.
• Various enumerated iterators mentioned earlier
• IndexSlice::position, IndexSlice::rposition as self.iter().position() will return a Option<usize>
