Adding `serde_stacker` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add serde_stacker

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

serde_stacker = "0.1.14"

The serde_stacker library will be automatically available globally. Read the serde_stacker library documentation.

Readme

Serde stack growth adapter

This crate provides a Serde adapter that avoids stack overflow by dynamically growing the stack.

Be aware that you may need to protect against other recursive operations outside of serialization and deserialization when working with deeply nested data, including, but not limited to, Display and Debug and Drop impls.

[dependencies]
serde = "1.0"
serde_stacker = "0.1"

Deserialization example

use serde::Deserialize;
use serde_json::Value;

fn main() {
    let mut json = String::new();
    for _ in 0..10000 {
        json = format!("[{}]", json);
    }

    let mut deserializer = serde_json::Deserializer::from_str(&json);
    deserializer.disable_recursion_limit();
    let deserializer = serde_stacker::Deserializer::new(&mut deserializer);
    let value = Value::deserialize(deserializer).unwrap();

    carefully_drop_nested_arrays(value);
}

fn carefully_drop_nested_arrays(value: Value) {
    let mut stack = vec![value];
    while let Some(value) = stack.pop() {
        if let Value::Array(array) = value {
            stack.extend(array);
        }
    }
}

Serialization example

use serde::Serialize;
use serde_json::Value;

fn main() {
    let mut value = Value::Null;
    for _ in 0..10000 {
        value = Value::Array(vec![value]);
    }

    let mut out = Vec::new();
    let mut serializer = serde_json::Serializer::new(&mut out);
    let serializer = serde_stacker::Serializer::new(&mut serializer);
    let result = value.serialize(serializer);

    carefully_drop_nested_arrays(value);

    result.unwrap();
    assert_eq!(out.len(), 10000 + "null".len() + 10000);
}

fn carefully_drop_nested_arrays(value: Value) {
    let mut stack = vec![value];
    while let Some(value) = stack.pop() {
        if let Value::Array(array) = value {
            stack.extend(array);
        }
    }
}
