proxy.golang.org: github.com/rusriver/zerolog

Package zerolog provides a lightweight logging library dedicated to JSON logging. A global Logger can be use for simple logging: NOTE: To import the global logger, import the "log" subpackage "github.com/rs/zerolog/log". Fields can be added to log messages: Create logger instance to manage different outputs: Sub-loggers let you chain loggers with additional context: Level logging Customize automatic field names: Log with no level and message: Add contextual fields to global Logger: Sample logs: Log with contextual hooks: Field duplication: There is no fields deduplication out-of-the-box. Using the same key multiple times creates new key in final JSON each time. In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt. Concurrency safety: Be careful when calling UpdateContext. It is not concurrency safe. Use the With method to create a child logger:
