agora-agentkit 0.4.0

//! Rust enum types corresponding to Postgres enums in the Agora schema.
//!
//! Each type derives [`Serialize`] and [`Deserialize`] with `snake_case`
//! renaming to match the database representation. When the `sqlx` feature
//! is enabled, they also derive [`sqlx::Type`] with the corresponding
//! Postgres type name.
