mir_slice.backward

Convenience function for backward indexing.

auto ref backward(size_t[N] index)
struct mir_slice(Iterator_, size_t N_ = 1, SliceKind kind_ = Contiguous, Labels_...)
ref return scope
@fmamath
auto ref
backward
()
(
size_t[N] index
)
if (
0 < N_ &&
N_ < 255
&&
!(
kind_ == Canonical &&
N_ == 1
)
&&
Labels_.length <= N_
&&
isIterator!Iterator_
)
auto ref backward(size_t[N] index)
auto ref backward(size_t[N] index)

Return Value

this[$-index[0], $-index[1], ..., $-index[N-1]]

Examples

import mir.ndslice.topology : iota;
auto s = iota(2, 3);
assert(s[$ - 1, $ - 2] == s.backward([1, 2]));
