This project is under active development. The underlying C# libraries are subject to change.
High-performance static structured logger with minimal allocations.
using var loggerRuntime = new LoggerRuntime().Initialize(builder => builder
.SetLevel(LogLevels.InfoAndAbove)
.AddTarget(SimpleLogContextRenderer.Instance, LoggerConsoleTarget.Instance)
.AddTarget(SimpleLogContextRenderer.Instance, new LoggerFileTarget("app_name", "./Logs")));
var logger = typeof(Program).CreateLogger(loggerRuntime);
logger.Info(static () => "PI is {PI}", static () => Math.PI.ToString("F"));Compare the performance of the Zero Logger with the NLog Logger.
