rustyschwab-types

Unofficial wire types for the Charles Schwab Trader and Market Data APIs (not affiliated with Charles Schwab & Co., Inc.): accounts, orders and transactions, quotes, option chains, price history, market hours, movers, and the streamer's messages and numbered field tables.

Most users want rustyschwab, the SDK, which re-exports these as rustyschwab::types. Depend on this crate directly to share the types without the HTTP and streaming stack.

[dependencies]
rustyschwab-types = "0.2"

Conventions

• Responses keep what they do not model. Response structs carry an extra map for fields Schwab adds, and response enums decode a value they do not know as Unknown rather than failing the whole payload.
• Requests are strict. OrderRequest rejects unknown fields, and validate() refuses what Schwab would reject or misread: Unknown enum values, fields that do not fit the order type, fractional equity or option quantities, extended-hours orders that are not limits, and more.
• Money is exact. Request prices and quantities are Decimal, read from a string such as "150.25" or a JSON number. Prices go out as strings and quantities as JSON numbers, the forms Schwab's examples use.
• Orders have constructors. OrderRequest::limit, stop, bracket, one_cancels_other and friends build Schwab's documented shapes, and OptionSymbol reads and writes OSI option symbols.

Features

• schemars: derives JsonSchema on the request types, for tool schemas (the schwab-mcp server uses it).
