Guaranteed lifetime of {input.begin(), input.end()} after an action ::apply() method

[0x8000-0000]

Regarding

https://github.com/taocpp/PEGTL/blob/main/doc/Actions-and-States.md?plain=1#L200

   More importantly the action_input does not own the data it points to, it belongs to
   the original input used in the parsing run. Therefore the validity of the pointed-to
   data might not extend (much) beyond the call to apply()!

I am creating (by hand for now) a parse tree, and I would like to record some "strings" cheaply in the nodes, using the result of input.string_view(). I understand they might dangle, but if my original input comes from pegtl::memory_input constructed from a string_view() over a buffer I own, can I safely assume that as long as that buffer is alive, all my references will point into it and will not dangle? I presume the pegtl::memory_input object can be destroyed. (It would make sense for it to be so, but just checking.)

Yes, that should work.
