pub struct Hook {
    pub name: String,
    pub callback: Box<Fn() -> Result<(), String>>,
}

Fields

name: String

The name of the hook to call

callback: Box<Fn() -> Result<(), String>>

Failures

Your function passed in needs to return a String on error so that users will know what happened. Ideally this should also be logged with juju::log
