Struct juju::Hook [−] [src]

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

Fields

name: String

The name of the hook to call

callback: fn() -> Result<(), String>

A function to call when Juju calls this hook

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
