`useHasSlice`

The useHasSlice primitive returns a boolean indicating whether a given Slice exists in an Index, and registers a listener so that any changes to that result will cause an update.

useHasSlice(
  indexId: MaybeAccessor<string>,
  sliceId: MaybeAccessor<string>,
  indexesOrIndexesId?: MaybeAccessor<undefined | IndexesOrIndexesId>,
): Accessor<boolean>

	Type	Description
`indexId`	`MaybeAccessor<string>`	The `Id` of a possible `Index` in the `Indexes` object.
`sliceId`	`MaybeAccessor<string>`	The `Id` of a possible `Slice` in the `Index`.
`indexesOrIndexesId?`	`MaybeAccessor<undefined \| IndexesOrIndexesId>`	The `Indexes` object to be accessed: omit for the default context `Indexes` object, provide an `Id` for a named context `Indexes` object, or provide an explicit reference.
returns	`Accessor<boolean>`	Whether a `Slice` with that `Id` exists.

This primitive follows the same Indexes object resolution rules as the useSliceIds primitive.
