replaceInto

Replace occurrences of from with to in subject and output the result into sink. changed counts how many replacements took place.

Parameters

sink Sink: an output range
subject E[]: the array to scan
from R1: the item to replace
to R2: the item to replace all instances of from with
changed size_t: the number of replacements

Examples

auto arr = [1, 2, 3, 4, 5];
auto from = [2, 3];
auto to = [4, 6];
auto sink = appender!(int[])();

size_t changed = 0;
replaceInto(sink, arr, from, to, changed);

assert(sink.data == [1, 4, 6, 4, 5]);
assert(changed == 1);
