Method split_at

src/pointer.rs:232–239

Splits the `Pointer` at the given index if the character at the index is a separator slash (`'/'`), returning `Some((head, tail))`. Otherwise, returns `None`. For the following JSON Pointer, the following splits are possible (0, 4, 8): ```text /foo/bar/baz ↑ ↑ ↑ 0 4 8 ``` All other indices will return `None`. ## Example ```rust # use jsonptr::Pointer; let ptr = Pointer::from_static("/fo

(&self, offset: usize)

    /// assert_eq!(ptr.split_at(3), None);
    /// ```
    pub fn split_at(&self, offset: usize) -> Option<(&Self, &Self)> {
        if self.0.as_bytes().get(offset).copied() != Some(b'/') {
            return None;
        }
        let (head, tail) = self.0.split_at(offset);
        // SAFETY: we split at a token boundary, so head and tail are valid pointers
        unsafe { Some((Self::new_unchecked(head), Self::new_unchecked(tail))) }
    }

    /// Splits the `Pointer` into the parent path and the last `Token`.
    pub fn split_back(&self) -> Option<(&Self, Token)> {
