Alias std.traits.Unsigned

alias Unsigned(T) = ModifyTypePreservingTQ!(Impl,OriginalType!T);


T A built in integral or vector type.


The corresponding unsigned numeric type for T with the same type qualifiers.

If T is not a integral or vector, a compile-time error is given.


static assert(is(Unsigned!(int) == uint));
static assert(is(Unsigned!(long) == ulong));
static assert(is(Unsigned!(const short) == const ushort));
static assert(is(Unsigned!(immutable byte) == immutable ubyte));
static assert(is(Unsigned!(inout int) == inout uint));


Unsigned types are forwarded

static assert(is(Unsigned!(uint) == uint));
static assert(is(Unsigned!(const uint) == const uint));

static assert(is(Unsigned!(ubyte) == ubyte));
static assert(is(Unsigned!(immutable uint) == immutable uint));
