    pub source: &'a HurtSource<'a>,

What Hooks::living_incoming_damage is told. Each field is that hook’s argument of the same name, described in the hook’s doc.

Fields

entity: i32

kind: &'a str

source: &'a HurtSource<'a>

victim: &'a Victim

weapon: Option<&'a ItemStack>

container: &'a mut DamageContainer

cancelled: bool

Whether the event is cancelled: by the game or an earlier listener, or by this one setting it. Only a listener that receives cancelled events (#[listener(receive_cancelled)]) sees true, and setting it back to false lets the game’s behaviour run.
