Crate waddling_errors_macros 

Procedural macros for waddling-errors

This crate provides convenient macros for defining error code components, primaries, and sequences with rich metadata support.

Macros

• component! - Define component enums with automatic ComponentId impl
• primary! - Define primary enums with automatic PrimaryId impl
• sequence! - Define sequence constants with metadata

Examples

use waddling_errors_macros::{component, primary, sequence};

component! {
    Auth,
    Database {
        docs: "Database operations",
        tags: ["backend"],
    },
}

primary! {
    Token,
    Connection {
        docs: "Connection errors",
    },

sequence! {
    MISSING(001) {
        description: "Item not found",
        hints: ["Check if item exists"],
    },
}
