frontTransversal

std range

Given a range of ranges, iterate transversally through the first elements of each of the enclosed ranges.

  1. struct FrontTransversal(Ror, TransverseOptions opt = TransverseOptions.assumeJagged)
  2. FrontTransversal!(RangeOfRanges, opt) frontTransversal(RangeOfRanges rr)
    FrontTransversal!(RangeOfRanges, opt)
    frontTransversal
    (
    TransverseOptions opt = TransverseOptions.assumeJagged
    RangeOfRanges
    )
    (
    RangeOfRanges rr
    )

Examples

import std.algorithm.comparison : equal;
int[][] x = new int[][2];
x[0] = [1, 2];
x[1] = [3, 4];
auto ror = frontTransversal(x);
assert(equal(ror, [ 1, 3 ][]));
