Beancount validation rules.

This crate implements validation checks for beancount ledgers:

• Account lifecycle (opened before use, not used after close)
• Balance assertions
• Transaction balancing
• Currency constraints
• Booking validation (lot matching, sufficient units)

Error Codes

All error codes follow the spec in spec/validation.md:

rustledger-validate

Beancount validation with 27 error codes for ledger correctness.

Error Categories

Example

use rustledger_validate::{validate, validate_with_options, ValidationOptions};

// Simple validation
let errors = validate(&directives);

// Validation with options
let options = ValidationOptions::default();
let errors = validate_with_options(&directives, options);

for error in errors {
    eprintln!("{}: {}", error.code(), error.message());
}

Features

• Parallel validation with rayon
• Configurable error severity
• Rich error messages with source locations
