## Exception safety
Strong guarantee: if an exception is thrown, there are no changes to any JSON pointer.
## Exceptions
- Throws [parse_error.107](https://json.nlohmann.me/home/exceptions/#jsonexceptionparse_error107) if the given JSON pointer `s` is nonempty and does not begin with a slash (`/`); see example below.
- Throws [parse_error.108](https://json.nlohmann.me/home/exceptions/#jsonexceptionparse_error108) if a tilde (`~`) in the given JSON pointer `s` is not followed by `0` (representing `~`) or `1` (representing `/`); see example below.
## Complexity
Linear in the length of `s`.
