Struct ComboField 

pub struct ComboField {
    pub name: String,
    pub required: bool,
    pub error_messages: HashMap<String, String>,
    pub widget: Widget,
    pub help_text: String,
    pub initial: Option<Value>,
    pub validators: Vec<Box<dyn FormField>>,
}

A field that combines multiple field validators

ComboField runs all provided validators in sequence and requires all to pass.

Examples

use reinhardt_forms::fields::ComboField;
use reinhardt_forms::{Field, CharField, EmailField};
use serde_json::json;

let mut email_field = EmailField::new("email".to_string());
let mut char_field = CharField::new("email".to_string());
char_field.min_length = Some(5);
char_field.max_length = Some(100);

let field = ComboField::new("email")
    .add_validator(Box::new(email_field))
    .add_validator(Box::new(char_field));

let result = field.clean(Some(&json!("user@example.com")));
assert!(result.is_ok());

let result = field.clean(Some(&json!("not-an-email")));
assert!(result.is_err());

let result = field.clean(Some(&json!("a@b")));
assert!(result.is_err());
