Enter templates. :)
auto clamp(T)(T value, T mini, T maxi) {
if (value >= maxi) {
return maxi;
}
if (value <= mini) {
return mini;
}
return value;
}
unittest {
assert(clamp("k", "d", "y") == "k");
assert(clamp(42, 10, 20) == 20);
assert(clamp(0.5, 1.5, 1_000) == 1.5);
}
void main() {
}
You can improve the function with template constraints.
