tripo-api 0.1.3

//! Shared typed enums used across request and response structs.
//!
//! Two flavors:
//! - `string_enum!` — strict. Unknown wire values fail to deserialize. Used
//!   for request payloads so typos in user-supplied config (RON, CLI args)
//!   surface as errors instead of silently becoming an `Unknown` variant.
//! - `string_enum_open!` — forward-compatible. Adds a `#[serde(other)]
//!   Unknown` catchall so new server-side values don't break response parsing.
