Error Codes Reference

Auto-generated from src/util/diagnostic/codes/

The YaoXiang compiler uses a unified error code system, where each error code contains:

• Code: Error identifier (e.g., E1001)
• Category: Compilation phase the error belongs to
• Title: Short description of the error
• Message: Detailed error message
• Help: Possible solutions

Error Code List

Prefix	Category	Description
E0xxx	Lexer/Parser	Lexer and parser errors
E1xxx	TypeCheck	Type checking errors

In Code

use yaoxiang::util::diagnostic::{ErrorCodeDefinition, I18nRegistry};

// Find the error code and retrieve title and help info via I18nRegistry
let i18n = I18nRegistry::default();

if let Some(code) = ErrorCodeDefinition::find("E1001") {
    let title = i18n.get_title(&code);
    println!("Title: {}", title);

    if let Some(help) = i18n.get_help(&code) {
        println!("Help: {}", help);
    }
