Return Value

Type: auto

lazy slice of the same kind and the same structure Note: Does not allocate neither new slice nor a closure.

Examples

import mir.ndslice.topology;

auto payload = [1, 2, 3, 4];
auto s = iota([payload.length], payload.ptr); // slice of references;
assert(s[1] == payload.ptr + 1);

auto c = *s; // the same as s.map!"*a"
assert(c[1] == *s[1]);

*s[1] = 3;
assert(c[1] == *s[1]);
