Crate use_api_error 

use-api-error

API error envelope primitives for RustUse.

Models error codes, messages, details, field errors, validation errors, retryability, categories, and protocol-neutral error envelopes.

Example

use use_api_error::{ErrorCategory, ErrorCode};

let value = ErrorCode::new("invalid-request").expect("valid API primitive");

assert_eq!(value.as_str(), "invalid-request");
assert_eq!(ErrorCategory::Validation.to_string(), "validation");

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 framework response conversion.
• No localization system.
• No exception handling runtime.
