Crate cor 

cor — Colorize JSON-structured log lines from stdin.

This library provides the core parsing and formatting functionality for the cor CLI tool. It can parse JSON log lines from various frameworks (logrus, zap, slog, pino, bunyan, structlog), auto-detect timestamp, level, and message fields, and output colorized human-readable text.

Example

use cor::{Config, format_line};

let config = Config::default();
let mut out = String::new();

format_line(r#"{"level":"info","msg":"hello","port":8080}"#, &config, false, &mut out);
assert!(out.contains("INFO"));
assert!(out.contains("hello"));
