LemonCore.Config.Logging (lemon_core v0.1.0)

View Source

Logging configuration for file output and log levels.

Inspired by Ironclaw's modular config pattern, this module handles logging-specific configuration including log file paths, levels, rotation settings, and compression options.

Configuration

Configuration is loaded from the TOML config file under [logging]:

[logging]
file = "./logs/lemon.log"
level = "debug"
max_no_bytes = 10485760
max_no_files = 5
compress_on_rotate = true
filesync_repeat_interval = 5000

Environment variables override file configuration:

  • LEMON_LOG_FILE
  • LEMON_LOG_LEVEL
