Struct StreamRuleLedger 

pub struct StreamRuleLedger {
    pub turn: u64,
    pub fired: BTreeMap<String, u64>,
}

User-turn counter plus the turn each stream rule last fired on.

Fields

turn: u64

User turns started in this session (1-based once a turn runs).

fired: BTreeMap<String, u64>

Rule name → turn of its last hit.

pub fn begin_turn(&mut self)

A new user turn starts.

pub fn last_fired(&self, name: &str) -> Option<u64>

Turn on which name last fired.

pub fn record(&mut self, name: &str)

Record a hit of name on the current turn.
