Module client 

Channel setup and authorized service clients.

FinamApi is the entry point: one lazily connecting channel plus one shared TokenManager. Every service client it hands out puts the current JWT into the authorization header of each call, so a client never holds an expired token.

Examples

use brokapi_finam_protocol::pb::grpc::tradeapi::v1::marketdata::QuoteRequest;
use brokapi_finam_protocol::{ApiEndpoint, FinamApi, start_token_manager};

// `endpoint` is `ApiEndpoint::default()` for the real broker, `secret` is your API secret.
let tokens = start_token_manager(&endpoint, secret, "my-app").await?;
let api = FinamApi::connect(&endpoint, tokens, false)?;

let quote = api
    .market_data()
    .last_quote(QuoteRequest { symbol: "SBER@MISX".into() })
    .await?
    .into_inner();
assert_eq!(quote.symbol, "SBER@MISX");
