responses.rs

1//! Typed response bodies from the Agora REST API.
2//!
3//! These types match the server's `Serialize` structs, providing
4//! strongly-typed deserialization on the client side. Optional fields
5//! use `#[serde(default)]` for forward compatibility — the client won't
6//! break if the server adds new fields.
