Macro itertools::iproduct
[−]
[src]
macro_rules! iproduct { (@flatten $I:expr,) => { ... }; (@flatten $I:expr, $J:expr, $($K:expr,)*) => { ... }; ($I:expr) => { ... }; ($I:expr, $J:expr) => { ... }; ($I:expr, $J:expr, $($K:expr),+) => { ... }; }
Create an iterator over the “cartesian product” of iterators.
Iterator element type is like (A, B, ..., E)
if formed
from iterators (I, J, ..., M)
with element types I::Item = A
, J::Item = B
, etc.
#[macro_use] extern crate itertools; // Iterate over the coordinates of a 4 x 4 x 4 grid // from (0, 0, 0), (0, 0, 1), .., (0, 1, 0), (0, 1, 1), .. etc until (3, 3, 3) for (i, j, k) in iproduct!(0..4, 0..4, 0..4) { // .. }
Note: To enable the macros in this crate, use the #[macro_use]
attribute when importing the crate:
