Parameters

collection Collection: range to be projected from
range Range: random access range to be projected to

Return Value

Type: IndexedRoR!(Collection, Range)

Range with a projection to range for every element of collection

Examples

import mir.ndslice.fuse;

auto perms = 2.permutations;
assert(perms.save.fuse == [[0, 1], [1, 0]]);

auto projection = perms.indexedRoR([1, 2]);
assert(projection.fuse == [[1, 2], [2, 1]]);

import mir.ndslice.fuse;
// import mir.ndslice.topology: only;

auto projectionD = 2.permutations.indexedRoR("ab"d);
assert(projectionD.fuse == [['a', 'b'], ['b', 'a']]);

// auto projectionC = 2.permutations.indexedRoR(only('a', 'b'));
// assert(projectionC.fuse == [['a', 'b'], ['b', 'a']]);
