Crate json_streamparse_rs 

json-streamparse-rs

Streaming JSON balance detector. Feed bytes incrementally and ask whether the buffer currently holds a complete top-level JSON value.

This is not a full parser; it’s the small utility you want when an LLM is producing JSON token-by-token and you need to know “can I hand this to serde_json::from_str yet?” without actually parsing every prefix.

String-aware (won’t be fooled by { inside a string literal), escape-aware (\\\" doesn’t end the string).

Example

use json_streamparse_rs::Balancer;
let mut b = Balancer::new();
b.push(b"{\"name\":\"Cl");
assert!(!b.complete());
b.push(b"aude\",\"v\":1}");
assert!(b.complete());
