waddling_errors/
lib.rs

1//! Ultra-minimal diagnostic code system for the Waddling ecosystem
2//!
3//! Provides a standardized 4-part diagnostic code format:
4//!
5//! **Format**: `SEVERITY.COMPONENT.PRIMARY.SEQUENCE`  `E.CRYPTO.SALT.001`
6//!
7//! # Quick Start
8//!
9//! ```rust
10//! use waddling_errors::prelude::*;
11//!
12//! const ERR_SALT: Code = error("CRYPTO", "SALT", 1);
13//! assert_eq!(ERR_SALT.code(), "E.CRYPTO.SALT.001");
14//! ```
15//!
16//! # Sequence Conventions
17//!
18//! The Waddling ecosystem uses semantic sequence numbers:
19//!
20//! | Sequence | Meaning    | Example                           |
21//! |----------|------------|-----------------------------------|
22//! | 001      | MISSING    | Required item not provided        |
23//! | 002      | MISMATCH   | Values don't match expected type  |
24//! | 003      | INVALID    | Format/validation failed          |
25//! | 021      | NOTFOUND   | Resource not found                |
26//! | 025      | CORRUPTED  | Data corruption detected          |
27//! | 031-897  | (project)  | Domain-specific sequences         |
28//! | 999      | COMPLETE   | Full completion                   |
29//!
30//! See `docs/SEQUENCE-CONVENTIONS.md` for complete list.

32//! # Error Registry Pattern
33//!
34//! ```rust
35//! // errors.rs - Project error registry
36//! pub mod errors {
37//!     use waddling_errors::prelude::*;
38//!     
39//!     pub const SALT_MISSING: Code = error("CRYPTO", "SALT", 1);
40//!     pub const KEY_LENGTH: Code = error("CRYPTO", "LENGTH", 2);
41//!     pub const DEPRECATED_SYNTAX: Code = warning("PARSE", "DEPR", 1);
42//! }
43//! ```
