Alias `std.typecons.ReplaceTypeUnless`

Like ReplaceType, but does not perform replacement in types for which pred evaluates to true.


						
				alias ReplaceTypeUnless(alias pred, From, To, T...) = T[0];

Example

import std.traits : isArray;

static assert(
    is(ReplaceTypeUnless!(isArray, int, string, int*) == string*) &&
    is(ReplaceTypeUnless!(isArray, int, string, int[]) == int[]) &&
    is(ReplaceTypeUnless!(isArray, int, string, Tuple!(int, int[]))
        == Tuple!(string, int[]))
);
