# use-api-request
API request metadata primitives for RustUse.
Models request IDs, correlation IDs, trace IDs, timestamp labels, sources, contexts, and protocol-neutral request envelopes.
## Example
```rust
use use_api_request::{RequestContextKind, RequestId};
let value = RequestId::new("req_123").expect("valid API primitive");
assert_eq!(value.as_str(), "req_123");
assert_eq!(RequestContextKind::User.to_string(), "user");
```
## 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 HTTP parsing.
- No clock access.
- No tracing backend integration.
