Enum member std.traits.isLvalueAssignable

Returns true iff an lvalue of type Rhs can be assigned to a variable of type Lhs.

enum isLvalueAssignable(Lhs, Rhs) = __traits(compiles, () { lvalueOf!Lhs = lvalueOf!Rhs; } );


struct S1
    void opAssign(S1);

struct S2
    void opAssign(ref S2);

static assert( isLvalueAssignable!(long, int));
static assert(!isLvalueAssignable!(int, long));
static assert( isLvalueAssignable!S1);
static assert( isLvalueAssignable!S2);
