Struct PatternValidator 

pub struct PatternValidator { /* private fields */ }

Pattern validator using regular expressions.

Implementations

impl PatternValidator

pub fn new( pattern: impl Into<String>, message: impl Into<String>, ) -> Result<Self>

Create a new pattern validator.

Errors

Returns error if the regex pattern is invalid.

pub fn new_default_message(pattern: impl Into<String>) -> Result<Self>

Create a new pattern validator with default message.

Errors

Returns FraiseQLError::Validation if the regex pattern is invalid.

pub fn from_compiled(regex: Regex, message: impl Into<String>) -> Self

Build a pattern validator from an already-compiled regex.

Used by create_validator_from_rule when the ValidationRule::Pattern variant has already compiled the pattern at construction time, so we avoid a redundant Regex::new call here.

pub fn validate_pattern(&self, value: &str) -> bool

Validate that a value matches the pattern.

Trait Implementations

impl Validator for PatternValidator

fn validate(&self, value: &str, field: &str) -> Result<()>

Validate a value and return an error if validation fails.
