Enum member std.traits.isMutable

Returns true if T is not const or immutable. Note that isMutable is true for string, or immutable(char)[], because the 'head' is mutable.

enum isMutable(T) = !is(T == const) && !is(T == immutable) && !is(T == inout);


static assert( isMutable!int);
static assert( isMutable!string);
static assert( isMutable!(shared int));
static assert( isMutable!(shared const(int)[]));

static assert(!isMutable!(const int));
static assert(!isMutable!(inout int));
static assert(!isMutable!(shared(const int)));
static assert(!isMutable!(shared(inout int)));
static assert(!isMutable!(immutable string));
