llm-output-parser

Production-grade parser for extracting structured data from LLM responses.

Handles think blocks, markdown fences, malformed JSON, and real-world model output without an additional LLM call.

Features

• Strip <think> blocks from LLM responses
• Extract JSON from markdown code fences
• Tolerant parsing of malformed JSON (trailing commas, single quotes, comments)
• No external LLM call needed — pure Rust parsing
• Optional YAML support behind the yaml feature

Usage

use llm_output_parser::parse_json;

let raw = "```json\n{\"key\": \"value\"}\n```";
let result: serde_json::Value = parse_json(raw).unwrap();
