[][src]Crate viperus

viperus is an (in)complete configuration solution for Rust applications.

I have already said that it is incomplete? use at your own risk. ;-) viperus handle some types of configuration needs and formats.

  • setting defaults
  • reading from JSON, TOML, YAML, dotenv file ,java properties config files
  • reading from environment variables
  • reading from Clap command line flags
  • setting explicit values
  • reload of all files
  • whatch config files and reolad all in something changes
  • caching Viperus uses the following decreasing precedence order.
  • explicit call to add
  • clap flag
  • config
  • env variables
  • default
