Struct SubIdGen 

pub struct SubIdGen(/* private fields */);

Hands out [SubscriptionId]s: 1, 2, 3, … (after start), never repeating.

The market data connector starts at 0 and the user data connector at 1000, so that ids from the two connectors of one process are easy to tell apart in logs. Thread safe.

Examples

use brokapi_finam::subs::SubIdGen;

let ids = SubIdGen::new(1000);
let first = ids.next();
let second = ids.next();
assert_ne!(first, second);

Implementations

impl SubIdGen

pub fn new(start: u64) -> Self

A generator whose first id is start + 1.

pub fn next(&self) -> SubscriptionId

The next unused id.
