Implementations

impl FormValidator

pub fn new() -> Self

Creates a new empty form validator.

pub fn field(self, name: impl Into<String>, validator: StringValidator) -> Self

Adds a required field rule with default error message (“This field is required”).

pub fn field_msg( self, name: impl Into<String>, validator: StringValidator, required_msg: impl Into<String>, ) -> Self

Adds a required field rule with a custom error message.

pub fn optional_field( self, name: impl Into<String>, validator: StringValidator, ) -> Self

If the field is not present or is empty, validation succeeds. If present and non-empty, the validator rules are executed.

pub fn validate<F: FormData + ?Sized>( &self, data: &F, ) -> Result<(), ValidationErrors>

Validates a form data payload, collecting all errors across all fields.
