Function ts_tree_cursor_goto_previous_sibling

pub unsafe extern "C" fn ts_tree_cursor_goto_previous_sibling(
    self_: *mut TSTreeCursor,
) -> bool

Move the cursor to the previous sibling of its current node.

This returns true if the cursor successfully moved, and returns false if there was no previous sibling node.

Note, that this function may be slower than ts_tree_cursor_goto_next_sibling due to how node positions are stored. In the worst case, this will need to iterate through all the children upto the previous sibling node to recalculate its position.
