core.internal.dassert

string _d_assert_fail(string op, A)(auto ref scope const A a);
Generates rich assert error messages for unary expressions
The unary expression assert(!una) will be turned into assert(!una, _d_assert_fail!"!"(una)). This routine simply acts as if the user wrote assert(una == false).
Parameters:
op Operator that was used in the expression, currently only "!" is supported.
A a Result of the expression that was used in assert before its implicit conversion to bool.
Returns:
A string such as "a != true" or "a == true".
string _d_assert_fail(string comp, A, B)(auto ref scope const A a, auto ref scope const B b);
Generates rich assert error messages for binary expressions
The binary expression assert(x == y) will be turned into assert(x == y, _d_assert_fail!"=="(x, y)).
Parameters:
comp Comparison operator that was used in the expression.
A a Left hand side operand.
B b Right hand side operand.
Returns:
A string such as "a $comp b".
