**Header:** `ClikaRT/compute/tensor.h`

A `[`[`start`](./IndexSlice.md#start)`, `[`stop`](./IndexSlice.md#stop)`, `[`step`](./IndexSlice.md#step)`)` range at one subscript position. Each slot is an [`IndexBound`](./IndexBound.md): an int literal, a 0-D/1-D integer [Tensor](../Tensor.md), or absent (open bound; absent [`step`](./IndexSlice.md#step) is 1). [`all`](./all.md#all) below is the fully-open slice.
