Attribute Macro main 

#[main]

Marks the entrypoint of a Witchcraft server.

This macro should be applied to a function taking 3 arguments: the server’s install config, a Refreshable of the server’s runtime config, and a mutable reference to the Witchcraft context object. It is a simple convenience function that wraps the annotated function in one that passes it to the witchcraft_server::init function.

Examples

use conjure_error::Error;
use witchcraft_server::config::install::InstallConfig;
use witchcraft_server::config::runtime::RuntimeConfig;
use witchcraft_server::Witchcraft;
use refreshable::Refreshable;

#[witchcraft_server::main]
fn main(
    install: InstallConfig,
    runtime: Refreshable<RuntimeConfig, Error>,
    wc: &mut Witchcraft,
) -> Result<(), Error> {
    // initialization code...
    Ok(())
}

Expands to:

use conjure_error::Error;
use witchcraft_server::config::install::InstallConfig;
use witchcraft_server::config::runtime::RuntimeConfig;
use witchcraft_server::Witchcraft;
use refreshable::Refreshable;

fn main() {
    fn inner_main(
        install: InstallConfig,
        runtime: Refreshable<RuntimeConfig, Error>,
        wc: &mut Witchcraft,
    ) -> Result<(), Error> {
        // initialization code...
        Ok(())
    }

    witchcraft_server::init(inner_main)
}
