Make find() constexpr in C++11 #48
Comments
|
I'd like to do so, can you hint on an implementation? |
|
@martinmoene : Is the naive implementation not ok for the constexpr case? |
|
@martinmoene : See #49 . |
|
@eyalroz thanks for your input! It helps to get me going :) |

@martinmoene : Do you think we could possibly use an immediately-invoked lambda instead of the function call? |
|
Not immediately ;) Can you explain what the driving idea behind that is? In C++14, one can create a recursive lambda, but not immediately invoke it. |
|
Right, we wouldn't be able to recurse. I just wanted to avoid the separate function outside the class, if it's only used in one place. |

Currently, the
find()method of basic_string_view is nssv_constexpr14. It seems to me it should be possible to make it constexpr since C++11 with tail-recursion iteration.The text was updated successfully, but these errors were encountered:
