Detailed Description

template<bool VALUE>
class clang::insights::Once< VALUE >

A helper object which returns a boolean value just once and toggles it after the first query.

This allows to simplify code like this:

bool first{true};
for(... : ...) {
  if(first) {
     first = false;
     ...
  } else {
    ...
 }

into this:

OnceTrue first{};
for(... : ...) {
  if(first) {
     ...
  } else {
    ...
 }
