  • implicitConvCommonTy

    Declaration

    pure nothrow @nogc @safe TY implicitConvCommonTy(TY ty1, TY ty2);

    If ty1 and ty2 are basic types, return the TY that both can be implicitly converted to.

    Parameters

    TY ty1

    first operand type

    TY ty2

    second operand type

    Return Value

    ty = common type, else Terror

  • implicitConvTy1

    Declaration

    pure nothrow @nogc @safe TY implicitConvTy1(TY ty1, TY ty2);

    If ty1 and ty2 are basic types, return the TY that ty1 can be implicitly converted to to bring them to a common ty. It's symmetric, i.e. the operands can be swapped.

    Parameters

    TY ty1

    first operand type

    TY ty2

    second operand type

    Return Value

    ty = what ty1 should be converted to, else Terror
