This deduction guide is provided for iota_view
For the definitions of /*is-integer-like*/ and /*is-signed-integer-like*/, see is-integer-like
Note that the guide protects itself against bugs arising from sign mismatch, like views::iota ( 0, v.size ( ) ) , where 0 is signed and v.size()
Example
#include <cassert> #include <ranges> int main() { auto io = std::ranges::iota_view(1L, 7L); // deduces W and Bound as “long” assert(io.front() == 1L and io.back() == 6L); }
