//! Domain error types for the IAM (auth) module.
|
||
|
|
//!
|
||
|
|
//! Typed error enums replace `anyhow::Result` in domain traits and
|
||
|
|
//! application services, enabling callers to match on specific error
|
||
|
|
//! variants (e.g. `NotFound` vs `Conflict`) rather than string-checking.
|
||
|
|
//!
|
||
|
|
//! # Components
|
||
|
|
//!
|
||
|
|
//! - [`RepositoryError`] — persistence-layer errors (not found, conflict, I/O)
|
||
|
|
//! - [`ServiceError`] — use-case / orchestration errors (config, state
|
||
|
|
//! mismatch, provider failures)
