# use-api-deprecation
API deprecation primitives for RustUse.
Models deprecation status, sunset date strings, replacement endpoints, migration notes, and warning labels with simple state helpers.
## Example
```rust
use use_api_deprecation::{DeprecationStatus, SunsetDate};
let value = SunsetDate::new("2026-05-25").expect("valid API primitive");
assert_eq!(value.as_str(), "2026-05-25");
assert_eq!(DeprecationStatus::Active.to_string(), "active");
```
## Scope
- Small validated types for API metadata.
- Stable display labels and conservative parsing helpers.
- Dependency-light primitives that can be reused by other RustUse crates.
## Non-goals
- No calendar math.
- No automatic migration.
- No policy enforcement.
