use-diagnostic-code

Stable diagnostic identifier primitives for RustUse.

Foundation

use-diagnostic-code provides DiagnosticCode, a small string-backed identifier for stable diagnostic names such as CONFIG001, VALIDATE_MISSING_FIELD, and DATA.INVALID_SHAPE.

Codes are trimmed at the edges, reject empty values, and preserve internal characters.

Example

use use_diagnostic_code::DiagnosticCode;

let code = DiagnosticCode::new(" VALIDATE_MISSING_FIELD ").unwrap();

assert_eq!(code.as_str(), "VALIDATE_MISSING_FIELD");
assert_eq!(code.to_string(), "VALIDATE_MISSING_FIELD");

Scope

• Codes are stable string identifiers.
• The crate does not reserve prefixes or parse domain-specific code systems.
• Rendering, logging, and error handling are out of scope.

Status

use-diagnostic-code is a pre-1.0 crate with a deliberately small API.
