 |
|
I use dmd 2 compilers and am uncertain if I write in my methods "const" or "in", because I have read that "in" is a shorthand for "const" in D 2.
Now I stand between the fronts, if i take | Code: | void foo(const ushort width) const {
//...
} |
or | Code: | void foo(in ushort width) const {
//...
} |
What is your meaning?
Or does this completely make no difference? |

I will probably use in future "in" instead of "const".
I had not thought that it lasts days, until somebody answers on my "either - or" question. Nevertheless, thank you  |

Howdy,
According to TDPL, "in" is a synonym for "const."
But for readability, "in" does not convey "this is never modified by the function" in quite the way that "const" does.
So I'd rather read code that had "const int x" instead of "in int x", since "const" tells me something without needing to check the manual.
