Configuration Presets

Log-only writes files without console output. Display-only writes console and rejects file sinks with error.FileStorageDisabled (no stray files created). Silent rejects everything.

// Files only
const logCfg = logly.Config.logOnly();
var logLogger = try logly.Logger.initWithConfig(allocator, logCfg);
defer logLogger.deinit();
_ = try logLogger.addSink(logly.SinkConfig.file("app.log"));

// Console only
const dispCfg = logly.Config.displayOnly();
var dispLogger = try logly.Logger.initWithConfig(allocator, dispCfg);
defer dispLogger.deinit();
// Returns error.FileStorageDisabled; no file created:
_ = dispLogger.addSink(logly.SinkConfig.file("nope.log")) catch {};

Output:

File sink correctly rejected: FileStorageDisabled (no file created)
