Crate rustyschwab_types 

Schwab Types

Type definitions for the Charles Schwab Trading and Market Data APIs.

This crate provides strongly-typed Rust structures for all API request and response types used by the Schwab APIs. These types are designed to:

• Provide type safety for API interactions
• Support serialization/deserialization via serde
• Match the official Schwab API documentation

Modules

• market_data - Quotes, price history, and market data types
• streaming - Real-time streaming WebSocket message types
• accounts - Account information and positions
• trading - Order types, transactions, and trading operations
• common - Shared enums and utility types

Example

Outbound orders use the strict trading::OrderRequest shape: unknown fields are rejected and prices/quantities are exact decimals. Build one with the constructors or deserialize the JSON Schwab documents.

use rustyschwab_types::Decimal;
use rustyschwab_types::trading::{OrderInstruction, OrderRequest, OrderRequestLeg, OrderType};

let order = OrderRequest::limit(
    OrderRequestLeg::equity(OrderInstruction::Buy, "AAPL", 10),
    Decimal::new(15025, 2),
);
assert_eq!(order.order_type, Some(OrderType::Limit));
order.validate().unwrap();

let same: OrderRequest = serde_json::from_value(serde_json::json!({
    "orderStrategyType": "SINGLE",
    "orderType": "LIMIT",
    "session": "NORMAL",
    "duration": "DAY",
    "price": "150.25",
    "orderLegCollection": [{
        "instruction": "BUY",
        "quantity": 10,
        "instrument": { "symbol": "AAPL", "assetType": "EQUITY" }
    }]
}))
.unwrap();
assert_eq!(serde_json::to_value(&same).unwrap(), serde_json::to_value(&order).unwrap());

Modules

accounts

Account information, positions, and balances. Account types including balances, positions, and user preferences.

common

Common types shared across multiple modules. Common types shared across multiple API modules.

market_data

Market data types including quotes, price history, and market hours. Market data types for quotes, price history, options, and instruments.

streaming

Real-time streaming WebSocket message types and subscription management. Real-time streaming WebSocket types for the Schwab Streamer API.

trading

Trading types including orders, transactions, and execution reports. Trading types including orders, transactions, and execution reports.

validation

Typed errors from request validation. Typed errors for request validation (OrderRequest::validate and the query-parameter validators).

Structs

Decimal

The exact-decimal type prices and quantities use, so callers do not need their own rust_decimal dependency to build orders. Decimal represents a 128 bit representation of a fixed-precision decimal number. The finite set of values of type Decimal are of the form m / 10^e, where m is an integer such that -2⁹⁶ < m < 2⁹⁶, and e is an integer between 0 and 28 inclusive.
