# use-api-auth
API authentication metadata primitives for RustUse.
Models auth scheme names, bearer token metadata labels, basic auth markers, API key locations, OAuth scope labels, and permission scopes without authenticating anything.
## Example
```rust
use use_api_auth::{ApiKeyLocation, AuthSchemeName};
let value = AuthSchemeName::new("Bearer").expect("valid API primitive");
assert_eq!(value.as_str(), "Bearer");
assert_eq!(ApiKeyLocation::Header.to_string(), "header");
```
## 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 token validation.
- No password handling.
- No authorization engine.
