1.21\n\nNo breaking changes will be made to exported APIs before v3.0.0.\n\n## 💡 Usage\n\nGoDoc: [https://pkg.go.dev/github.com/samber/slog-datadog/v2](https://pkg.go.dev/github.com/samber/slog-datadog/v2)\n\n### Handler options\n\n```go\ntype Option struct {\n\t// log level (default: debug)\n\tLevel slog.Leveler\n\n\t// datadog endpoint\n\tClient  *datadog.APIClient\n\tContext context.Context\n\tTimeout time.Duration\t// default: 10s\n\n\t// source parameters\n\tService    string\n\tHostname   string\n\tGlobalTags map[string]string\n\n\t// optional: customize Datadog message builder\n\tConverter Converter\n\t// optional: custom marshaler\n\tMarshaler func(v any)

[]string{\"error\", \"err\"}\n```\n\n### Example\n\n```go\nimport (\n\t\"github.com/DataDog/datadog-api-client-go/v2/api/datadog\"\n\tslogdatadog
