rustledger-validate

Beancount validation with 26 error codes for ledger correctness.

Error Categories

Example

Validation is run through a ValidationSession. Standalone callers (LSP, FFI, tests on already-booked input) drive the two phases plus finalize directly; the loader pipeline interleaves booking between phases.

use rustledger_validate::{ValidationOptions, ValidationSession};
use rustledger_core::{Directive, naive_date};

let directives: Vec<Directive> = vec![/* parsed + booked input */];
let today = naive_date(2030, 1, 1).unwrap();

let session = ValidationSession::new(ValidationOptions::default());
let (session, mut errors) = session.run_early(&directives, today);
let (session, late_errors) = session.run_late(&directives, today);
errors.extend(late_errors);
errors.extend(session.finalize());

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

The previous free-function shortcuts (validate, validate_with_options) were removed in #1116 when validation was split around booking. Callers must now thread state through a ValidationSession so that Phase::Late sees the inventory state accumulated during Phase::Early.

Features

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