Provide some example of using a custom parser in a grammar ?

[sandwoodK]

Please apologies / feel free to correct if terminology is not good.

I've read (but can't find it anymore) that Lexy has the ability to switch to a completely hand written rule.

Let's assume that at some point I need to call a (provided) function with following signature
parseToSomeStuff(InputIterator & it, const InputIterator & end)

this function update the it to the last consumed value.

The issue is that end Iterator is not provided.

What would you recommand ?
