Function diff 

pub fn diff(old: &Statute, new: &Statute) -> DiffResult<StatuteDiff>

Computes the diff between two statutes.

Examples

use legalis_core::{Statute, Effect, EffectType, Condition, ComparisonOp};
use legalis_diff::diff;

let old = Statute::new(
    "tax-credit",
    "Tax Credit for Seniors",
    Effect::new(EffectType::Grant, "Tax credit granted"),
).with_precondition(Condition::Age {
    operator: ComparisonOp::GreaterOrEqual,
    value: 65,
});

let mut new = old.clone();
new.title = "Enhanced Tax Credit for Seniors".to_string();

let result = diff(&old, &new).unwrap();
assert_eq!(result.changes.len(), 1);
assert!(result.changes[0].description.contains("Title"));

Errors

Returns DiffError::IdMismatch if the statute IDs don’t match.
