StructConf

Combine argument parsing with a config file at compile time.

StructConf is a small derive macro that allows you to combine argument parsing from clap and config file parsing from rust-ini at compile time. It's inspired by the argument parser structopt.

StructConf aims to be relatively small and simple. Here are its current selling points:

• Options available in the config file, argument parser, both, or none.
• Configurable option names.
• Custom types supported.
• Optional fields with Option.
• Custom default expressions.
• Insightful error messages.
• Thoroughly tested.

Small example:

```rust use structconf::{clap, StructConf};

[derive(Debug, StructConf)]

struct ServerConfig { #[conf(help = "The public key")] pub publickey: String, #[conf(nofile, long = "your-secret", help = "Your secret API key")] pub secret_key: String, #[conf(default = "100", help = "timeout in seconds")] pub timeout: i32, }

pub fn main() { let app = clap::App::new("demo"); let conf = ServerConfig::parse(app, "config.ini"); println!("Parsed config: {:#?}", conf); } ```
