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[]))
);
