rs_limitless 0.1.1

//! Request and response model types for the Limitless Exchange API.
//!
//! All REST API responses are fully typed with concrete structs matching
//! the API's JSON shape. WebSocket event types and order types are also
//! fully typed for compile-time safety.
//!
//! # Convention
//!
//! - Field names use `snake_case` in Rust and `camelCase` on the wire via
//!   `#[serde(rename = "...")]` where needed.
//! - Numeric fields that arrive as JSON strings use `serde_helpers` to
//!   deserialize transparently.
