Struct PatternRule 

pub struct PatternRule { /* private fields */ }

Validates a string against a compiled regular expression (full-string match).

The pattern is anchored with ^...$ so that it must match the entire value, mirroring XSD <xs:pattern> behaviour.

Examples

use mx20022_validate::rules::pattern::PatternRule;
use mx20022_validate::rules::Rule;

let rule = PatternRule::new("COUNTRY_CODE", "[A-Z]{2}").unwrap();
assert!(rule.validate("GB", "/path").is_empty());
assert!(!rule.validate("gb", "/path").is_empty());
assert!(!rule.validate("GBR", "/path").is_empty());

Implementations

impl PatternRule

pub fn new(rule_id: impl Into<String>, pattern: &str) -> Result<Self, Error>

Build a new PatternRule with the given rule id and regex pattern.

The pattern is automatically anchored — do not include ^ / $ yourself.

Errors

Returns an error if pattern is not a valid regular expression.

pub fn pattern(&self) -> &str

The raw (unanchored) pattern string used to construct this rule.

Trait Implementations

impl Rule for PatternRule

fn id(&self) -> &str

Unique identifier for this rule (e.g. "IBAN_CHECK").

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

Run the rule against value at the given path and return any findings.
