Saving a struct with itself as data member in disk

Hi all,

I need to store a vector of string on disk. And I have to do this thing mulitiple times. So, to reduce the size of data on disk I have converted that vector of string into a Trie data structure (As I just need search operation not exact string).
This is my Trie data structure

pub struct TrieNode {
    pub children: HashMap<u8, TrieNode>,
    pub is_word: bool,

I was using SaveFile to do all the writing in disk. As it is highly performant and I need to write whole trie again and again after some time to disk .But its is giving me Error :
thread 'test_logic' has overflowed its stack
fatal runtime error: stack overflow

I know it has something to do with nested structure, Is there any way around thi problem?
Thanks for help :slight_smile:

As far as I understand this issue on GitHub Stack-overflow for recursive data-structures · Issue #25 · avl/savefile · GitHub, you are not just encountering a problem here because the data is deeply nested, right?

You could try to just use serde instead.
