Struct DurationField 

pub struct DurationField {
    pub name: String,
    pub required: bool,
    pub error_messages: HashMap<String, String>,
    pub widget: Widget,
    pub help_text: String,
    pub initial: Option<Value>,
}

A field for ISO 8601 duration validation

Validates that the input is a valid ISO 8601 duration format (e.g., “P1Y2M3DT4H5M6S”).

Examples

use reinhardt_forms::fields::DurationField;
use reinhardt_forms::Field;
use serde_json::json;

let field = DurationField::new("duration");

// Valid duration
let result = field.clean(Some(&json!("P1Y2M3DT4H5M6S")));
assert!(result.is_ok());

// Another valid duration (1 day)
let result = field.clean(Some(&json!("P1D")));
assert!(result.is_ok());
