Struct Ledger 

pub struct Ledger { /* private fields */ }

Event ledger for tracking photon event chains.

Maintains a record of all photon events with:

• Source mappings (src_map): Named sources mapped to source IDs
• Event chains (next/prev): Linked lists of event sequences
• Start events (start_events): Root events, which have no previous event cause

Implementations

impl Ledger

pub fn new() -> Self

pub fn start_events(&self) -> &Vec<Uid>

pub fn insert_start(&mut self, uid: Uid)

pub fn insert( &mut self, prev_event: Uid, next_event: Uid, next_next_seq_no: u32, )

pub fn get_next_seq_id(&self, uid: &Uid) -> Option<u32>

pub fn get_next(&self, uid: &Uid) -> Vec<Uid>
