Struct ValidationErrors 

pub struct ValidationErrors { /* private fields */ }

Collection of validation errors keyed by field name

Examples

use acton_htmx::forms::ValidationErrors;

let mut errors = ValidationErrors::new();
errors.add("email", "is required");
errors.add("email", "must be a valid email address");
errors.add("password", "must be at least 8 characters");

assert!(errors.has_errors());
assert_eq!(errors.for_field("email").len(), 2);
