agentic-logger (Rust)

AgentLogger for Rust. Emits byte-compatible JSONL via a custom serde_json formatter (": " / ", " separators, no \u escaping) so the Python query layer reads it unchanged.

Install

[dependencies]
agentic-logger = "0.1"

(Local build: cargo build. Depends only on serde, serde_json, uuid.)

Usage

use agentic_logger::{AgentLogger, ErrorCode};
use serde_json::json;

let lg = AgentLogger::new("my_agent", Some("build"), "./logs", None)?;
lg.info("Processing started", Some("parser"))?;
lg.info_full("with ctx", Some("net"), None, None, None,
             Some(json!({"endpoint": "/x"})))?;
lg.tool_call("bash", "npm install", 0, 1234, None, None, Some("added 50 pkgs"), None, None)?;
lg.error("Build failed", Some("build"), ErrorCode::ExecNonZero, Some("tb_abcd1234"))?;
lg.file_op("write", "/p/f.rs", true, Some(2048), None, None, Some(5), None)?;
lg.decision("use_redis", Some(&["redis","memcached"]), Some("perf"), Some(0.85), Some("arch"), None)?;

Notes

• pid stored as a string; seq/dur/exit/size as unquoted numbers.
• ISO 8601 timestamps computed dependency-free (no chrono), UTC +00:00.
• module is a required parameter (no stack introspection in stable Rust); defaults to "unknown" when None.
• Run tests: cargo test. Run the sample emitter: cargo run --example rust_emit -- <dir>.
