Crate brokapi_tbank_protocol 

Low-level T-Bank (T-Invest) API wire protocol: the gRPC client generated from the official .proto.

This is the protocol layer of the T-Bank connector. It knows how to talk to the broker and nothing about orders, books or events. The connector crate brokapi-tbank sits on top of it and turns these messages into the shared brokapi-core types. Use this crate directly only when you need a call the connectors do not wrap.

• v1 - generated messages, enums and gRPC clients. Every service and method of the official contract is generated. Their documentation comes from the .proto comments.
• TbankConfig - endpoint (production, sandbox or a local mock), token, account, timeouts.
• TbankClient - one shared HTTP/2 channel with Bearer-token authorization. Each accessor (for example TbankClient::orders) returns a ready generated client.
• AuthInterceptor - the piece that adds authorization: Bearer <token> to every request.
• money - Quotation and MoneyValue (units and nano) converted to and from Decimal, without f64 on the way.
• ProtocolError - configuration and transport errors raised while building the channel.

The full guide is in the book: https://brokapi.ru/docs/.

Examples

The example below starts the in-process T-Bank mock, builds a client for it and lists the accounts the token can see. Nothing touches the network and no money is involved.

use brokapi_tbank_protocol::{TbankClient, TbankConfig};

// In real code: `TbankConfig::sandbox("t.your-token")` or `TbankConfig::production(..)`.
let client = TbankClient::new(&cfg)?;
let accounts = client.list_accounts().await?;
assert!(!accounts.is_empty());
for account in &accounts {
    println!("account {}", account.id);
}
