Struct RuleRegistry 

pub struct RuleRegistry { /* private fields */ }

A registry of named validation rules.

Rules are stored by their Rule::id. When multiple rules share an ID the last one registered wins (use unique IDs unless intentional override is needed).

Examples

use mx20022_validate::rules::RuleRegistry;

let registry = RuleRegistry::with_defaults();
let errors = registry.validate_field("GB82WEST12345698765432", "/path/iban", &["IBAN_CHECK"]);
assert!(errors.is_empty());

Implementations

impl RuleRegistry

pub fn new() -> Self

Create an empty registry.

pub fn with_defaults() -> Self

Create a registry pre-populated with all built-in rules.

Built-in rules included:

• IBAN_CHECK — IBAN format + mod-97
• BIC_CHECK — BIC/SWIFT format
• CURRENCY_CHECK — ISO 4217 currency code
• COUNTRY_CHECK — ISO 3166-1 alpha-2 country code
• LEI_CHECK — ISO 17442 LEI format + mod-97
• AMOUNT_FORMAT — ISO 20022 decimal amount format
• DATETIME_CHECK — ISO 8601 datetime
• DATE_CHECK — ISO 8601 date

pub fn register(&mut self, rule: Box<dyn Rule>)

Register a rule. If a rule with the same ID already exists it is replaced.

pub fn get(&self, rule_id: &str) -> Option<&dyn Rule>

Look up a registered rule by ID.

pub fn validate_field( &self, value: &str, path: &str, rule_ids: &[&str], ) -> Vec<ValidationError>

Run a specific subset of rules (identified by rule_ids) against value at path and return all findings.

Rules whose IDs are not present in the registry are silently skipped.

Examples

use mx20022_validate::rules::RuleRegistry;

let registry = RuleRegistry::with_defaults();
let errors = registry.validate_field("NOT_AN_IBAN", "/doc/iban", &["IBAN_CHECK"]);
assert!(!errors.is_empty());

pub fn validate_all(&self, value: &str, path: &str) -> Vec<ValidationError>

Run all registered rules against value at path.

impl Default for RuleRegistry

fn default() -> Self
