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
